IMPORTANCE OF CHEMISTRY
TO DAILY LIFE
OBJECTIVES
At the end of this class, you should be able to;
Relate the importance of chemistry to daily life
Describe the role of chemistry to society and
technology
Cite contribution of chemistry to other sciences like
geology, agriculture, medicine, nutrition, etc.

Chemistry is the study of matter, its
properties, how and why substances
combine or separate to form other
substances. Here’s a look at the
importance of chemistry and why you
should study it.
What is Chemistry?
What is Chemistry?
Chemistry has a reputation for being a
complicated and boring science, but for the
most part, that reputation is undeserved.
Fireworks and explosions are based on chemistry, so
it’s definitely not a boring science.
What is Chemistry?
If you take classes in chemistry, you’ll apply math
and logic, which can make studying chemistry a
challenge if you are weak in those areas.
However, anyone can understand the basic of how things
work… and that’s the study of chemistry. In a nutshell, the
important of chemistry is that it explains the world
around you.

CHEMICAL REACTIONS HAPPEN WHEN
a car is started
tarnish is removed from silver
fertilizer is added to help plants grow
food is digested
electricity is produced from burning
natural gas
rust is formed on iron nails

EVERYTHING IN OUR LIVES FROM
MATERIALS TO LIFE INVOLVE CHEMISTRY
glass (SiO2)n
metal alloys
chemically treated water
plastics and polymers
baking soda, NaHCO3
foods
fertilizers and pesticides
living beings

CHEMICALS IN TOOTHPASTE
Chemistry Explains…
Food Preservatives
Food preservatives prevent spoilage of
food due to microbial growth. The most
commonly used preservatives include
table salt, sugar, vegetable oils and
sodium benzoate, C6H5COONa. Sodium
benzoate is used in limited quantities and
is metabolized in the body. Salts of sorbic
acid and propanoic acid are also used as
preservatives.
Chemistry Explains…
About chemistry in cosmetics
Cosmetics are substances used to enhance the
appearance or odor of the human body. A subset of
cosmetics is called "make-up“, which refers to
products intended to change the user's appearance.
There are still health concerns regarding the presence
of harmful chemicals within these products. Lipsticks
and lip balm contain oils, beeswax and perfumes.
These protect, soften and brighten the lips. Nail polish
polish is made of lacquer, and consists of polymers,
solvents, plasticizer's, colorants, and perfumes.
Mascaras have a composition based on a volatile
solvent, beeswax, pigments (iron oxide) and filming
polymers
Chemistry Explains…
Industries and Transport From cloth mills, lather
factories, petro-chemical industries and refineries to
metal industries- all use numerous fuels for power
generation and chemical products for processing their
product and improve the equality and simultaneously
produce pollution. Now-a-days chemical effluent
treatment plants use chemicals to control or neutralist
he hazardous impact of pollutants produced by the
industries. Aviation and shipping industries generate
power through power plants which burn fuels. Petrol
and diesel emit out green house gases dangerous for
the survival on earth which damage the ozone layer
that protects us from UV rays. As a result global
warming has taken place which is a destroyer of the
planet earth. But again Chemistry paves the way with
bio-fuels.
Chemistry Explains…
Science and Technology
The destructive effects of Atom Bombs
dropped on Hiroshima and Nagasaki?
Generations in Japan have suffered the
devastation and there has-been no solace. The
threat of weapons of mass-destruction
(WMDs) like the Nuclear, Chemical and
Biological weapons looms large on the
Humanity. Terrorists are using RDX and other
explosives to run currents
Chemistry Explains…
Medicine
Chemistry is a huge part of medicine,
both as a diagnostic and treatment
tool. Chemistry departments in
hospital medical labs analyze blood,
urine, etc. for proteins, sugars and
other substances. Blood analysis test
the amount of potassium and sodium
in our blood.
Chemistry Explains…
Chemistry Explains…
Cooking
Chemistry explains how food changes as
you cook it, how it rots, how to preserve
food, how your body uses the food you eat,
and how ingredients interact to make food,
Chemistry Explains…
Cleaning
Part of the importance of chemistry is to explains
how cleaning works. You use chemistry to help
decide what cleaner is best for dishes, laundry,
yourself, and your home. You use chemistry when
you use bleaches and disinfectants and even
ordinary soap and water. How do they work?
That’s chemistry!
Chemistry Explains…
Medicine
You need to understand basic chemistry so you
can understand how vitamins, supplements,
and drugs can help or harm you. Part of the
importance of chemistry lies in developing and
testing new medical treatments and medicines.
Chemistry Explains…
Environmental Issues
Chemistry is at heart of environmental issues. What
makes one chemical a nutrient and another chemical
a pollutant? How can you clean up the environment?
What processes can produce the things you need
without harming the environment?

Environmental Issue
Chemistry is at the heart of environmental issues. What
makes one chemical a nutrient and another chemical a
pollutant? How we can clean up the environment? What
processes can produce the things our need without
harming the environment? We're all chemists. We use
chemicals every day and perform chemical reactions
without thinking much about them. Chemistry is
important because everything you do is chemistry! Even
our body is made of chemicals. Chemical reactions occur
when we breathe, eat, or just sit there reading. All matter
is made of chemicals, so the importance of chemistry is
that it's the study of everything.
Chemistry Explains…
Scientists have created an organized way of doing what we all do every
day.
They follow a series of steps in order to verify their results.
These step-by-step investigations are called “experiments” or
“investigations.”
Every experiment has in it a control.
The control is what the results of the experiment are compared to in
order to determine what, if anything occurred.
SCIENTIFIC PROCESS
Chemistry Explains…
THE SCIENTIFIC METHOD
The scientific method is the process used
to explain observations in nature.
The method involves:
making observations
forming a hypothesis
doing experiments to test the hypothesis
Chemistry Explains…
1. Ask a QUESTION or identify a problem.
2. Gather information and form a HYPOTHESIS.
3. Create an Hypothesis
4. Test Your Hypothesis by Doing an Experiment
5. Analyze Your Data and Draw a Conclusion
6. SHARE your findings.

  • 11. About chemistry in cosmetics Cosmetics are substances used to enhance the appearance or odor of the human body. A subset of cosmetics is called "make-up“, which refers to products intended to change the user's appearance. There are still health concerns regarding the presence of harmful chemicals within these products. Lipsticks and lip balm contain oils, beeswax and perfumes. These protect, soften and brighten the lips. Nail polish polish is made of lacquer, and consists of polymers, solvents, plasticizer's, colorants, and perfumes. Mascaras have a composition based on a volatile solvent, beeswax, pigments (iron oxide) and filming polymers Chemistry Explains…
  • 12. Industries and Transport From cloth mills, lather factories, petro-chemical industries and refineries to metal industries- all use numerous fuels for power generation and chemical products for processing their product and improve the equality and simultaneously produce pollution. Now-a-days chemical effluent treatment plants use chemicals to control or neutralist he hazardous impact of pollutants produced by the industries. Aviation and shipping industries generate power through power plants which burn fuels. Petrol and diesel emit out green house gases dangerous for the survival on earth which damage the ozone layer that protects us from UV rays. As a result global warming has taken place which is a destroyer of the planet earth. But again Chemistry paves the way with bio-fuels. Chemistry Explains…
