The Importance of Chemistry in Daily Life
Most people have chosen to write their essay about how chemistry has played an important role in
everyday life. I have chosen to ask, how doesnt it play a role in everyday life? The simple fact is that
chemistry plays an important role in every persons daily activities from the moment were born.So what role does chemistry really play in everyday life? Well, this involvement usually begins first
thing each morning. Most people wake up to an alarm or radio. These common household items
contain batteries, which make them very chemically dependent. These batteries contain positive and
negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of
carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important
role in the discovery and understanding of materials contained in these and many other common
household items. Things like household cleaners and water purification systems are vitally dependent
on chemistry. Without chemistry something as simple as scrubbing a toilet without fear of severe
burns or small explosions might not be possible.
Next, though it isnt widely known, chemistry is also heavily involved with the manufacturing of things
such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals
such as cetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair
and skin. Without chemistry, these materials (or combinations of these materials) might be hazardous
or might not exist. The chemical coloring agents used in makeup and nail polish would not be possible
without an understanding of the chemicals involved.
Almost anything you do during the course of a normal day involves chemistry in some way. The gas
and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used everyday,
burning wood or other fossil fuels, chemistry is all around you each and every day. The associations
are practically limitless. So, as you go about your daily activities, remember to thank chemistry. As my
teacher always says, remember, "CHEMISTRY IS LIFE!"

Importance of chemistry
Chemistry has a reputation for bein! a complicated and borin! science# but for the most part#
that reputation is undeserved. 0irewor"s and e$plosions are based on chemistry# so it2s
definitely not a borin! science. If we ta"e classes in chemistry# we2ll apply math and lo!ic#
which can ma"e studyin! chemistry a challen!e if we are wea" in those areas. owever#
anyone can understand the basics of how thin!s wor"... and that2s the study of chemistry. In
a nutshell# the importance of chemistry is that it e$plains the world around us.
Chemistry e$plains how food chan!es as we coo" it# how it rots# how to preserve food# how
our body uses the food we eat# and how in!redients interact to ma"e food.
3art of the importance of chemistry is it e$plains how cleanin! wor"s. &e use chemistry to
help decide what cleaner is best for dishes# laundry and our home. &e use chemistry when
we use bleaches and disinfectants and even ordinary soap and water. ow do they wor"
That2s chemistry1
&e need to understand basic chemistry so we can understand how vitamins# supplements#
and dru!s can help or harm us. 3art of the importance of chemistry lies in developin! and
testin! new medical treatments and medicines.
Chemistry is at the heart of environmental issues. &hat ma"es one chemical a nutrient and
another chemical a pollutant ow can we clean up the environment &hat processes can
produce the thin!s we need without harmin! the environment
In this lens I2d li"e to tal" you about the Chemistry of daily life. Chemistry is an e$citin!
e$perimental science which lets us to understand our world and ma"es our life easier. +s
you will read in the followin! articles# chemistry is in our everyday life4 in our body# at home#
in the nature... in every second of our lives1
If any of you have a 5uestion about the chemistry of your everyday life# please feel free to
contact me# and I will publish here the answers to those that may be interestin! for most of
the people. I invite you also to leave a comment in my !uestboo" below.
Than" you very much to the S5uidoo staff for selectin! this lens on +pril 67th as the 2lens of
the day2# I feel honoured1 I invite you also to visit my other lens4 Spain in depth# and my
website. Than" you18reetin!s from Spain#

ow soap cleans
There are substances which can be dissolved in water )salt for e$ample*# and others that
can2t )for e$ample oil*. &ater and oil don2t mi$ to!ether# so if we try to clean an oily stain
from a cloth or from the s"in# water is not enou!h. &e need soap.
Soap is formed by molecules with a ,head, which li"es water )hydrophilic* and a lon! chain
which hates it )hydrophobic*.
9ecause of this dualism# soap molecules act li"e a diplomat# improvin! the relationship
between water and oil. ow &hen soap is added to the water# the hydrophilic heads of its
molecules stay into the water )they li"e it1*# while the lon! hydrophobic chains :oin the oil
particles and remain inwards )escapin! from the water*. In that way# they form circular
!roups named micellas# with the oily material absorbed inside and trapped.
+n emulsion of oil in water is then formed# this means that the oil particles become
suspended and dispersed into the water. Thus# those oil particles are liberated from the cloth
or the s"in# and the emulsion is ta"en away with the rinsin!.
In summary# soap cleans by actin! as an emulsifier. It allows oil and water to mi$ so that oily
!rime can be removed durin! rinsin!.There are more thin!s involved in this process# such as
for instance chan!es in the superficial tension of water# but this is the !eneral idea.
