Chemistry is present in everyday life through foods, air, cleaning products, emotions, and all objects. Some common examples of chemistry include water, table salt, nail polish remover, table sugar, battery acid, and vinegar. Many chemical reactions also occur in daily life through photosynthesis, cellular respiration, rusting of iron, digestion, combustion, soap cleaning, baking soda and vinegar reactions, carbonation, acid rain, ant bites, fruit ripening, and flowers. Chemistry plays a vital role in providing necessities like food, medicine, fuels, and materials through various chemical processes and compounds.

4. INTRODUCTION
Chemistry is a big part of our everyday life. We find
chemistry in daily life in the foods we eat, the air we
breathe, cleaning chemicals, our emotions and literally
every object we can see or touch. Some common
chemistry may be obvious, but others might surprise
us. Chemistry happens in the world around us, not just
in a lab. Chemistry is happening everywhere.

5. WHAT IS CHEMISTRY?
 Chemistry is the study of matter- its composition,
structure, properties, transformation from one form to
another, and the energy that accompanies its transaction.

6. CHEMISTRY IN EVERYDAY LIFE
Chemistry plays a very vital
role in our everyday life. Our
daily need of food, shelter,
medicine etc. are connected
with chemical compounds,
processes and principals.

9. CHEMISTRY IN OUR DAILY LIFE

10. COMMON CHEMICAL COMPOUNDS
 Water- H2O
 Table Salt- NaCl
 Nail polish remover- CH3COCH3
 Table Sugar- C12H22O11
 Battery acid- H2SO4
 Vinegar- C2H4O2
 Soaps- C₁₇H₃₅COONa
 Washing Soda- Na2CO3 .10H2O
 Bleaching Powder- NaClO
10

11. HAVE WE EVER THOUGHT WHAT IS
INSIDE OUR BODY?
 Most of the human body is
made up of water, H2O, with
cells consisting 72% water by
weight.
 99% of the mass of human
body is made up of just 6
elements: oxygen, carbon,
hydrogen, nitrogen calcium and
phosphorous.
11

12. WHAT IS INSIDE TALC POWDER?
 Talcum powder is a soft, white powder developed from
talc or magnesium silicate, a mineral composed primarily
of magnesium, silicon and oxygen
12

13. WHAT IS INSIDE A NAIL POLISH
REMOVER?
 A less harsh nail polish remover is ethyl acetate
13

14. WHAT IS BATTERY ACID?
 Battery acid is sulfuric acid (H2SO4)
14

15. WHAT IS AN ANTACID?
 Antacid is Sodium bicarbonate -NaHCO3, Aluminum
hydroxide -Al(OH)3 and Magnesium hydroxide- Mg(OH)2

16. EVERYDAY CHEMICAL
REACTIONS
16

17. HOW PLANTS PRODUCE FOOD?
 Plants apply
a chemical reaction
called photosynthesis
to convert carbon
dioxide and water
into food (glucose)
and oxygen. It's one
of the most common
everyday chemical
reactions and also
one of the most
important.
17

18. HOW ENERGY IS PRODUCED BY
CELLS?
 Glucose is combined with oxygen we breathe to release
energy needed by our cells plus carbon dioxide and
water. Energy used by cells is chemical energy in the
form of ATP. Here is the overall equation:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (36 ATPs)
18

19. WHY IRON DECAYS WHEN IT IS KEPT
OUTSIDE FOR A LONG TIME?
 Iron decays because of rusting when it is kept outside
 Over time, iron develops a red, flaky coating called
rust. This is an example of an oxidation reaction . Here
is the chemical equation for the rusting of iron:

20. WHAT HAPPENS WHEN FOOD GOES INSIDE
OUR STOMACH?
 Thousands of chemical reactions take place
during digestion.
 As soon as we put food in our mouth, an enzyme
in our saliva called amylase starts to break down
sugars and other carbohydrates into simpler
forms our body can absorb.
 Hydrochloric acid in our stomach reacts with
food to break it down, while enzymes break
proteins and fats.
20

21. WHAT HAPPENS WHEN WE STRIKE A MATCH, BURN
A CANDLE OR BUILD A FIRE?
 Every time we strike a match, burn a candle or build a fire,
we see the combustion reaction.
 In combustion, hydrocarbon and oxygen reacts and produce
carbon dioxide and water.
For example, the combustion reaction of methane is given
below:
21

22. HOW SOAPS CLEAN DIRT?
 Soaps and detergents
clean by way of
chemical reactions.
 Soap emulsifies dirt,
which means oily
stains bind to the
soap so they can be
lifted away with
water.
 Detergents act as
surfactants, lowering
the surface tension of
water so it can
interact with oils,
isolate them, and
rinse them away.
22

23. WHAT HAPPENS WHEN WE COMBINE
BAKING SODA WITH VINEGAR?
 If we combine vinegar and baking soda for a chemical
volcano in a recipe we experience a double displacement. The
ingredients recombine to produce carbon dioxide gas and
water. The carbon dioxide forms bubbles in the volcano
and helps baked goods rise. The reaction is given below:
23

24. WHY BUBBLES ARE LOST WHEN WE LEAVE
A SODA CAN OPEN FOR A LONG TIME?
 If we leave a soda can open for a long time, the carbonic
acid (the fizz) decompose into carbon dioxide and water.
Basically, we will lose the bubbles from our carbonated
beverage
24

25. WHY RAIN BECOMES ACIDIC?
 Acid rain caused by a chemical reaction that begins when
compounds like sulfur dioxide and nitrogen oxides are released into
the air from mills and factories.
 These substances can raise high into the atmosphere, where they
mix and react with water, oxygen and other chemicals to form more
acidic pollutants known as acid rain.
25

26. WHY WE CHERT IS APPLIED ON SKIN
WHEN ANTS BITE?
 When ants bite, they leave formic acid (H-COOH) on our skin.
It irritates our skin.
 Chert is a kind of base. So if it is applied on the affected area it
neutralizes formic acid to some extent. So the irritation ends.
26

27. WHY WATER BECOMES COLDER WHEN
GLUCOSE IS ADDED TO IT?
 Dissolution of glucose in water is an Endothermic process.
 In thermodynamics, the word “endothermic” refers to a
process or reaction in which the system absorbs energy from
its surroundings in the form of heat.
 Thus, when some glucose is added to water, the water glucose
system absorbs energy from its surroundings to form heat for
the dissolution of glucose to take place.
 Consequently the temperature of water decreases, thereby
making it colder.
27

28. WHY LEMON TASTES SOUR?
The sour taste of a lemon is
caused by the presence of
organic acids. The major acid
in lemons is citric acid, which
constitutes around 5 to 6% of
the lemon’s juice.
28
Other acids are also present but in
much lower concentrations than
citric acid. Malic acid is one of
those.

29. WHY ONION MAKES US CRY?
 Chopping or slicing of an onion
breaks down its cells
 Amino acids and enzymes mix,
creating sulfur chemicals that
evaporate easily
 Sulfur compounds spread through
the air and irritates the eyes
 Older onion create this effect most
strongly
29

30. HOW FRUITS RIPE?
30

31. CHEMISTRY OF FLOWERS
 Smell a flower (the fragrance is
chemistry)
 See a flower (the colors are
chemistry)
 Touch a flower (the structure is
chemistry)
31

32. CONCLUSION
In the end we can say that chemistry is all around us, but
the only thing is that we need to observe it carefully and
notice everything around us. We should appreciate the
work of scientists who observed those things and bought it
to us.
