CHEM 123, General Chemistry I Laboratory Fall 2021

Dr. Nahla Hatab Course Instructor: Dr. Nahla Hatab (nabuhata@utk.edu) Stockroom Manager: Mr. Noah Hathcock Lab Director: Dr. Nahla Hatab (nabuhata@utk.edu) Lab Times / Sections / Schedule: The full schedule will be posted on Canvas and on Labflow. Please download a copy and keep a printed copy of this schedule for easy reference. Or better yet, put the schedule into your phone! Note: When you send email Dr. Hatab, a course number, a section number and a subject MUST be included in the email subject area (eg. “Chem 123, section 005, subject”).

Pre-& CO-Requisites: You must be registered for CHEM122.

I. If you decide to drop CHEM122 any time during the semester, you will be automatically dropped from CHEM123. You will not be re-enrolled in CHEM123 if YOU drop the course.

II. If you would like to stay enrolled in CHEM123 while dropping CHEM122, you will need to send an email AFTER the 10th Wednesday of the semester to either Linda Sherman (lsherman@utk.edu) or the lab instructor (nabuhata@utk.edu) to complete the withdrawal process for you. You MUST regularly attended your CHEM122 classes/exams up to the 10th Wednesday of the semester in order to be considered for continued CHEM123 enrollment.

Introduction to the CHEM 123 Lab The emphasis in lab will be on interpreting correct results, development of technique, and broader applications. Your grade in lab is based on attendance, pre-lab quizzes, the lab notebook, and post-lab reports/quizzes. You must wear safety goggles during all lab exercises and dress appropriately.

Mask Policy According to University guidance on wearing face coverings, students and employee are required to wear masks in classrooms and laboratories, and at indoor academic events required for students.

Attendance & Absences If you do not attend the first scheduled lab day, you will be removed from the course. See the university policies for details. ABSENCES There are two types of absences:

● Excused – An excused absence is defined in the syllabus and is based on the university absence policies established in Hilltopics (https://hilltopics.utk.edu/academics/). See ATTENDANCE below.

● Unexcused – An unexcused absence is any absence not described by the syllabus or university absence policies.

Students are expected to attend every scheduled lab session. If a student is absent or not allowed to complete a lab, a UEX (unexcused absence) grade will be recorded. If you obtain,

● 1 UEX grade – you will forfeit 10 % of your course grade. ● 2 UEX grades – the grade for the entire course will be reduced by 25%. ● 3 UEX grades – the grade for the entire course will be reduced by 40%. ● 4 (or more) UEX grades this will result in receiving a failing grade (an “F”) for the entire course.

ATTENDANCE Attendance is mandatory for successful completion of this course. You are expected to attend all scheduled labs at the designated times. If you are absent from the first lab of the semester, you will be dropped from the course. Any exceptions will require all necessary documentation according to university regulations. If you miss a lab, you must complete an “excused absence form” (https://chem.utk.edu/chem-103113123133-lab-excused-absence-form/) and submit the form for the absence to be excused. Incomplete forms or improperly completed forms will not be processed. Any requests for make-up labs 5 days after the missed lab will not be accepted unless there are approved, extenuating circumstances. All absences require written, official documentation. See below for specific instances and clarification on absences: If you miss lab for a University sanctioned activity:

● Submit a copy of the documentation and your completed excuse form to the instructor 7 days prior the day of absence.

If you miss lab due to illness:

● Contact your TA and the instructor immediately by email to let them know you will miss lab. ● Complete the excused absence form and submit a digital copy of your doctor’s note.

Death in the immediate family / primary provider or care-giver:

● Provide documentation, typically an obituary or in some instances the facilities for the service will provide written documentation, or see below for other acceptable options.

All other instances of absence from lab ● Require a signed letter from a university advisor, mentor, counselor, or Dean of Students or will require

another formal document as arranged by the instructor in order to excuse the absence. No exceptions. These instances include professional development, death outside of the immediate family, military duty, or any instance in which your academic advisor deems acceptable. These situations will be taken on a case-by-case basis.

What to do when you have an excused absence: ● Fill out the lab make-up form found online at (https://chem.utk.edu/chem-103113123133-lab-

excused-absence-form/) Arriving late to lab: You are considered late to lab if you arrive after your TA starts the pre-lab lecture.

1. Arriving late to lab constitutes an unexcused absence. If you are 10 minutes late to lab the door of your lab will be locked and you will not be allowed to complete the lab experiment for the day and will receive an Unexcused Absence for the day, pending any concerns which may fall under the excused absence policy.

2. TAs will take attendance at the start of the pre-lab lecture. If you are not present for attendance, you will not be allowed in the lab for that experiment.

3. Leaving Lab early: Under normal circumstances, there should be no reason to leave lab early. However, if you need to leave lab early because you are not feeling well or for some emergency, you will need to provide an excused absence form as soon as possible or you will receive a 0 for the lab

report. For all other instances, there are no acceptable excuses for being dismissed from the lab unless explicit permission is given by the lab director. If there is a schedule conflict, a written excuse (as previously discussed) will be required and it will not be necessary for you to attend lab for that session, and a make-up lab should be arranged.

Four or more unexcused absences during the semester will result in an automatic “F” in the course. THE SHORT STORY = DO NOT MISS LAB. MAKEUP LABS AND EXCUSED ABSENCES Make-up labs are only offered DURING the week where the lab experiment is being completed. After the lab experiment is completed for the week (see schedule online) there will be no more opportunities to complete the lab and it will be counted as a UEX, unless there are extenuating circumstances. All students must complete 90% of the labs for the semester. If you have an approved absence there are 2 outcomes:

1. For the first excused absence of the semester, there will be no make-up lab assigned. Your lab grade will be calculated using your completed labs for the semester.

2. For any absence after the first excused absence of the semester, you will need to complete the lab during the week where labs are being run, or you will forfeit your in-lab grade for the experiment. a. Known absences. (Military orders, court-imposed legal obligations, religious observances, and

participation in university, college, or unit sponsored activities that lead to clear experiential and educational outcomes)

i. For known absences (absences > 1 for semester) any approved make-up labs need to be scheduled, approved, and completed during the week where the lab experiment is being performed. For instance, if you know that you will be absent on a Friday, complete the lab BEFORE that date. Check the schedule posted online to see what experiments are running on which days. Any known absences which are not approved prior to the absence will be counted as a UEX.

b. For each absence, you will need to fill out the excused absence form as described previously. c. You are expected to complete all approved make-up labs. If you fail to complete a lab for any

reason, even if it is an excused absence, it will count as an unexcused absence. d. If you fail to attend your scheduled make-up lab time, you will need to provide documentation and

go through the approval process again, just as with any missed lab provided you fall within the time constraints.

Lab make-up policies are different during the summer sessions due to the compressed schedules. Please see the relevant announcements on Canvas regarding these changes.

Supplies (MANDATORY) 1. Two Lab Notebooks – Two composition notebooks can be purchased any store that sells office

supplies. These notebooks do not have to be expensive notebooks but must be bound so that the pages cannot be torn out. NO three-ring binders or wire-coiled binders.

GRADED COMPONENTS OF THE LAB There are three graded components to each lab, and they will account for a total of 100% of your course grade. PRE-LAB QUIZZES (25%) Before each lab every week, there will be a short quiz (5 questions) to be completed online. You will need a cell phone, tablet, iPad, or laptop to take the pre-lab quiz. The quiz is based on the material in the lab manual, pre-lab lecture, and any additional assigned reading material from your textbook. The pre-lab quiz will be available 24 hours before the lab and you can take it anytime. BUT once you start you will have 10 minutes to finish it. POST-LAB REPORTS (50%) Each laboratory meeting will involve an experiment and a digital post-lab report. There are 13 post-lab reports, each worth 100 points. The post lab report consists of a report (75 points) and a post lab quiz (25 points). You will have 20 minutes to finish the post lab quiz once you start. The digital post-lab report will require you to enter data, graph, perform calculations, and complete post-lab questions. The post-lab report is submitted electronically, it will be due at 8:00 AM on the following week’s lab day. Post-lab report grades will be posted on Canvas and Top Hat on a weekly basis. NOTE: The work on your lab report must be YOUR OWN original work. You may work together with a lab partner to understand the calculations, but you cannot directly copy calculations or text. Copying another person’s lab report is considered cheating and will be dealt with according to the academic integrity policies of UTK. LAB NOTEBOOK (25%) All labs are considered to be “closed book”. This means that you can only use your lab notebook and a printed hard copy of the procedure while performing the lab. The point of the closed-book format is to make you read through and understand the entire experiment before you execute it in lab.

Maintaining a proper notebook leads to a safe, productive lab period and accurate report results. In addition, this will also help with preparing for the pre-lab quiz and help you form questions to ask in the pre-lab lecture before starting on the procedure. GRADING SCALE (%)

Note: These letter grade assignments are subject to change, but only in the direction beneficial to the students. A NOTE ABOUT LATE ASSIGNMENTS Extensions are only granted for university approved reasons. An assignment is considered late if it is not submitted by 8:00 AM on the day of your lab. Extensions due to any technology problem such as computer crash, upload or download problems, Canvas & Labflow availability or quiz timeouts will not be granted. It is your responsibility to make sure that all work is correctly completed and submitted by the deadline. Emailed copy will NOT be accepted. No exceptions.

QUALITATIVE ANALYSIS: IDENTIFYING PROPERTIES ON UNKNOWN SOLIDS 11. ENERGY CHANGES AND TRANSFERS 12. TRENDS IN DATA

Maintaining a Laboratory Notebook - Guidelines EXPECTATIONS You are expected to read and understand all assigned materials before lab. YOU MUST HAVE YOUR LAB Notebook every day you come to lab. If you arrive without your lab notebook, you will be asked to go retrieve it before you will be allowed in the lab. Repeat offenses will result in a minimum of 30 points deducted from notebook grade. If you do not have a lab notebook by the start of the third experiment of the semester you will not be allowed to participate in the lab due to safety concerns. GENERAL PROTOCOL FOR KEEPING A LABORATORY NOTEBOOK (BEFORE THE FIRST LAB).

1. Purchase two bound composition book. Loose or perforated pages, three-ring notebooks, or spiral notebooks are not acceptable.

2. Record your name, course, section, and TA name on front of each notebook. 3. Reserve the first two pages for a Table of Contents (TOC). 4. Number the pages on the top right corner of the page. 5. All entries must be recorded in ink. Do not erase or use “white-out” to make corrections. A mistake is

not erased, but crossed out with a single line so that it is still legible and replaced with the corrected information recorded above it. In scientific practice, the goal is to write a notebook such that a different scientist can use your notes to replicate your experiment, even years later.

6. Use all pages (front and back) so there are no blank or missing page. PRIOR TO LAB EACH WEEK…. Before lab every week print a hard copy of the procedure and prepare your notebook (in ink) with the following information.

1. Experiment title, date, lab partner. 2. Purpose including concepts covered in the experiment. 3. Procedure

The procedure should be a condensed list of the steps you will take in lab and should not exceed three pages. The condensed procedure should be detailed enough to have anyone repeat the lab using your notebook. When drafting the lab procedure in your notebook, the goal should be that anyone should be able reproduce your experiment using the procedure and notes that you have recorded in your notebook. DO NOT re-write the lab procedure verbatim from the digital lab manual. The process of deciding what to include in your notebook and what is simply repetition will result in understanding what is going on when you perform the lab.

4. Cite all information sources following the citation guidelines in your lab manual. 5. Summary of chemicals, hazards, and safety.

Create a table of the chemicals used in the lab and associated hazards or safety precautions associated with them. This information can be found:

● Documents Topic-block: Course page on labflow.com ● Chemical Company Website:

o www.sigmaaldrich.com ● Search Engine: Type the chemical name + MSDS into a search engine (like google)

A list of the chemicals for which you MUST look up hazards is listed on a document which is located on labflow.com. You can access this information by looking up the Material Safety Data Sheets (MSDS, alternatively known as SDS) for the chemicals. This safety section is not an exhaustive description of the hazards, rather what are the main hazards. For instance, if we look at the hazards for sodium hydroxide (NaOH), we would list the hazards as ‘Skin contact hazard. Caustic.’ This information can be found in a couple of ways: Type the chemical name + MSDS into a search engine (like google) You will notice that most chemicals list the following (or some permutation of) as hazards: “Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation.” Understand that each chemical from the required list was selected for a specific reason as to why I am asking you to look up its MSDS. What makes this one chemical unique? Pay attention and do NOT simply write “Skin contact hazard.” for every chemicals. Not sure what to do? Send an email to your TA and ask for help! Or visit the General Chemistry tutorial center.

6. Waste handling. Add a comment in your notebook regarding the proper disposal and handling of waste for the chemicals.

Figure 1. Sample notebook pages. DURING LAB…. ● Record a complete and organized list of data obtained during the experiment.

o ALL raw data obtained in the laboratory are recorded (including units) directly into your lab notebook at the time the data are obtained.

o Recording data on loose scraps of paper is unacceptable; such loose scraps of paper may be confiscated.

● A sample calculation should be included in your notebook for each type of calculation. Remember, someone else will read these data, and you will need them for calculations and digital reports.

● Recording data in tabular form is strongly urged. ● All other observations that you make during the course of the experiment should also be recorded.

Examples include: color changes, changes that you make in the procedure, observed errors such as titrating past the end point. If you are in any doubt as to whether an observation is relevant, make a note of it in your notebook. Do not trust your memory!

● Your notebook must be sufficiently neat that someone else can read and understand it. Use plenty of space. If you have difficulty writing legibly, print instead. Remember, you will have to extract data from your notebook to calculate results and write reports.

● The TA will check your notebook as you enter the lab every week. ● The TA will check and sign your notebook at the end of lab every week. ● The lab notebooks will be collected and graded 3 times a semester; week of experiment 3, week of

experiment 7, and after the last experiment.

CONSEQUENCES FOR INCOMPLETE PREPARATION OR LACK OF ORIGINALITY If you do not have your notebook completed at the start of the pre-lab discussion, you will be required to complete it before being allowed in the lab. After the pre-lab lecture, you will complete your notebook. After your TA approves the late notebook, you will begin work on your experiment on your own, without a partner. You will lose 5 points from your notebook grade from that experiment. The written work in your lab notebook must be YOUR OWN original work. You may work together with a lab partner to understand the calculations, but you cannot copy calculations or text. Unauthorized obtaining of or photocopying another person’s lab notebook is considered cheating and will be dealt with according to the academic integrity policies of UTK.

Lab Notebook Rubric A completed lab notebook must be presented to your TA at the beginning of every lab. The TA will look for a complete written procedure for the experiment of the day. You must have a complete procedure before being allowed into the room to complete the experiment. Lab notebooks will be collected and graded 3 times per semester: the weeks of experiment 4 and 7, and after the final experiment. TABLE OF CONTENTS (5 PTS)

● First two pages, clear up to date table of content. ● All pages are numbered. ● Ink is used for all the writing.

TOTAL POINT DISTRIBUTION FOR EACH EXPERIMENT (95 PTS)

Component Description Points Awarded Title of experiment, date experiment was experiment was completed, and name of lab partner. 2.5

Clear, concise purpose expressing an understanding of the intent, concepts, and methods for the experiment. 5

The purpose should be an original expression, not a statement taken from the digital lab manual or other source. Read the experiment and think about what the overall goal. It is usually easier to complete the purpose AFTER you write the procedure and read through the introduction/background for the experiment.

10

Clearly and legibly written procedure. 10 All major, relevant steps of procedure should be expressed, condensed to a maximum of three pages. 15

Proper ordering of procedure steps. 5 Name and concentrations of chemicals used. Amounts of chemicals to be used. 5 Summary of any hazard the chemicals present based on the table of hazards for the chemicals indicated in the document posted here bluedoorlabs. 5

Liquid waste disposal entry indicating proper disposal procedure, described in lab manual.

Solid waste disposal entry indicating proper disposal procedure, described in lab manual. 5

A complete and neat listing of data taken during the experiment. Data must be properly identified and labeled (including units) and presented in logical order. 15

All other observations made during the course of the experiment should also be recorded. (10 pts) 10

Sample calculation for each type of calculation required for the lab. 5 Signature of TA after the completion of every lab. 2.5

Please make sure you are looking up the information for the correct chemicals. Some labs use a large number of chemicals, but you don’t need info for ALL of them. You do not need to include instructions dealing with setup/calibration of Vernier LabQuest systems. A simple statement such as “Collect temperature data using Vernier LabQuest 3” would suffice.

Additional Important Laboratory Information LAB ATTIRE In brief, proper lab attire consists of safety goggles, closed-toe shoes with socks, loose fitting long pants, and a solid shirt which covers your torso and shoulders. Safety glasses are not acceptable. Please see the safety section for more details.

Safety Safety rules and regulations are strictly enforced in the chemistry lab. Be aware that ignoring these safety guidelines can not only impact your safety, or that of your fellow students; it could also have an impact on your lab grade for that day. SAFETY RULE VIOLATIONS Safety regulations are put in place in an effort to minimize the risk to you while you are working in the lab. Safety is our number one concern for you while you are in the labs. All rules below must be followed without exception. Violations of the rules below will result in the following cumulative penalties which will be assessed for EACH violation in the lab:

1st offense (per day) 20 points deducted from your lab report grade. 2nd offense 50 points deducted from your lab report (70 points cumulative). 3rd offense 0 points awarded on all assignments and dismissal from the lab.

1. Everyone must wear goggles whenever ANYONE in the lab is handling chemicals or glassware or “doing

an experiment.”= ALWAYS!!! If you are in the lab and are not wearing your goggles properly, you will be penalized according to the rules outlined above.

a. Goggles are distinct from safety glasses in that they make a seal around the eyes. Goggles are required while in the teaching labs. Safety glasses are not appropriate PPE.

2. NO CELL PHONES are allowed. Cell phones are not allowed for any reason in the lab. They may not be used as calculators, periodic tables, timers/clocks, or to access reference material. Not only are cell phones easily contaminated by chemicals, they are also a safety hazard as they are a distraction to you. If the TA see a cell phone out, then student will lose 20 points from the digital post-lab grade.

a. You must wear proper attire while in the lab. See the section below. b. If you arrive to lab and do not have proper attire, you will not be allowed into the lab c. If you are told to leave the lab due to do attire, you may return to lab after you have acquired

the proper attire. (You have ~ 30 minutes…etc) d. When you return you will be required to work individually to complete the lab. You may NOT

join with another group and simply use their data/experiments upon returning. e. You will not be given any additional time to complete the lab. f. If you do not return, you will be given a 0 for the in lab assignments for the day, however it is

not considered an unexcused absence. g. Proper behavior and professional attitude should be maintained. This includes following all

instructions from your TA, the stockroom personnel, or any faculty member present in the labs. ADDITIONAL SAFETY – PROPER ATTIRE Proper attire and good chemical hygiene are required for all students. The following are NOT proper attire!

1. Shoes You must wear CLOSED-TOE, SOLID shoes. This rule is interpreted to mean solid “tennis-shoe” type sneakers. Anything that falls into the category of a “sandal” is not allowed – including but not limited to: flip-flops, Teva-type sandals, Tom’s shoes/sandals, toe-shoes, “Mexican” (Huarache)-style sandals (that may have closed-toes but lots of leather straps) or athletic footwear that have lots of holes on the sides (even though the toes are technically covered). Women’s “dress” shoes that reveal a large portion of the foot are also not allowed (even though they are “closed-toed and solid”).

a. If you enter the lab wearing inappropriate shoes, you will be asked to leave. You MAY return to complete experiment. However, you must return within 30 minutes and note the following:

i. You will not be given additional time to complete the lab. ii. You will have to complete the lab experiment on your own. You may NOT join with

another group and simply use their data/experiments upon returning. 2. Socks

Socks need to be worn with your shoes. This is to provide an additional layer or protection if a spill occurs.

i. Socks do NOT constitute leg covering. You may not pull up your socks to count as “long pants” (see below).

ii. Socks are not an approved way to cover feet. Wearing socks with open top shoes does not constitute a “solid” shoe.

3. Other Clothing You must wear LOOSE FITTING, LONG PANTS. Jeans or khakis made from cotton are the preferred type of pants for the lab. Long pants must be worn to provide an additional level of safety for you in the event of a chemical spill. Long pants means they should cover down to your shoes, with no skin being exposed. In general, this rule will not be difficult to follow during the winter months, but it will also be strictly enforced during the summer months. a. If you enter the lab wearing shorts or other inappropriate dress, you will be asked to leave. You

MAY come back and complete the experiment. However, you must return within 30 minutes and note the following:

i. You will not be given additional time to complete the lab. ii. You will have to complete the lab experiment on your own. You may NOT join with

another group and simply use their data/experiments upon returning.

iii. A pair of medical scrubs can be worn over your shorts or other pants. Warm-up style athletic wear, “yoga” pants, leggings, or any other tight-fitting clothing is not acceptable. The following are NOT accepted pants:

iv. Socks are not an approved way to cover parts of your legs to constitute “long pants”.

4. Hair Long hair must be tied back. Long hair must be held in place by a hair tie or some other approved method of securing it. The strap of your goggles do NOT count as a method for securing your hair.

5. Food, Drink, and Backpacks

a. There is no eating, drinking, or chewing gum in the chemistry laboratory. Multiple offenses, as outlined previously, will result in you being asked to leave the laboratory and you will get a “0” on the experiment.

b. Place book bags, purses, and personal items in the cubbies located in the lab. ADDITIONAL CLASS RULES

6. Lab Glassware and Equipment a. Glassware and other equipment will be provided for you while in the laboratory. While in the

laboratory, broken equipment or glassware is the responsibility of the user. b. Special glassware and equipment: For some lab experiments, it is necessary to use glassware and

equipment not located in the labs. This glassware and equipment will be provided for you for use during the appropriate lab experiment. This glassware and equipment, while in your control/possession, is your responsibility and falls under the equipment replacement policy. A fee will be assessed if they are damaged or broken.

CHEMICALS Remember – in the Chemistry laboratory, you are working with hazardous chemicals. Almost every chemical you are using is listed in some way as being hazardous or toxic. We VERY STRICTLY enforce the safety rules as a way of keeping you safe and minimizing accidental exposure. If you have special medical circumstances that impact your ability to be in the chemistry laboratory such as pregnancy or other conditions, you MUST inform the instructor for the course. Failure to do so will be in violation of the safety contract signed at the beginning of the semester. Some labs use certain chemicals or items which may cause allergic reactions to people sensitive to these compounds (nut allergies, aspirin, iodine, etc.). As you are reading through the pre-labs, pay close attention to the chemicals which will be used and inform your TA and the lab director immediately if there are any medical concerns.

Therefore, such facilities are not exempt from the rules and regulations of this law. Students in laboratory classes of the University shall have as part of their curriculum instruction orientation to laboratory safety, including notification of the requirements of the Hazardous Communication Right-to-Know Act." Requirements for completion of this chemistry course necessitate that each student handles or uses certain chemicals. Some of these may have an adverse effect on the health of a fetus. This is especially true for the first trimester of pregnancy, but later trimesters of pregnancy are susceptible as well. The current state of

knowledge of the effects of chemicals on pregnancies is such that we cannot clearly state that any given chemical is completely safe, while another is not safe. Although protective equipment and lab procedures are designed to minimize contact with all chemicals in this lab, some exposure is possible. If pregnant, you are advised to consult with a physician regarding the completion of this course at this time. A list of chemicals will be furnished to your physician upon request to the Lab Director.” The Lab Director reserves the right to revise, alter, or amend this syllabus as necessary. Students will be notified in writing / email of any such changes.
