Chemicals that indicate the presence of a certain substance by changing color when they are in contact with that substance. A change in color = Positive Result (the substance is there) NO change in color = Negative Result (the substance is NOT there) 3 Chemical Indicators in this Lab: Benedicts Solution: Changes color when it comes in contact with a Monosaccharide like Glucose Iodine: Changes color when it comes in contact with a Polysaccharide like Starch Buiret Solution: Changes color when it comes in contact with a Protein Negative Control = Water The variable that is the same for all test trials. It is guaranteed to give a Negative Result Why use water? Why must we do Part I BEFORE Part II? What does Part I tell us so that we can do Part II? Note: in Part II you are completing the SAME procedures for Part I, BUT you are using McMush instead of the pure solutions so for every test, you will test the McMush and the Water Procedural Notes: Each team member should be the leader for 2 of the 4 tests When using the Hot Plate and Boiling the water - NO Messing Around Lilliana Anthony Brunyr Kendra Marie AaronMarcus CarlaChristine Rockens JhonAmanjot Julian Karen Jason JoeObayannaAmandoGarlyn Crystal JonathanAsarel Jamesly McSeating Chart Put on your apron and goggles before starting the lab!
