This document discusses acids and bases. It defines acids as sour tasting substances that produce hydrogen ions and turn litmus red. Common acids include those found in vinegar, citrus fruits, and other foods. Bases are defined as bitter tasting and soapy substances that turn litmus blue. Common bases include baking soda, detergents, and antacids. The document also explains how litmus paper can be used as a natural indicator to test whether a substance is acidic or basic by changing color.
Light travels in a straight line and can be reflected, refracted, or absorbed when it hits different materials and surfaces. Reflection occurs when light bounces off a surface like a mirror, following the laws of reflection. Refraction is when light changes direction as it passes from one medium to another, like from air to water. Lenses and curved mirrors can form real or virtual images by refracting or reflecting light rays. Prisms disperse white light into a spectrum due to refraction, demonstrating that light is made of different colors.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like depression and anxiety.

This document provides information about various life processes including nutrition, respiration, and photosynthesis. It defines nutrition as the process of taking in food and utilizing it for growth, repair and energy. There are two main modes of nutrition - autotrophic (plants making their own food via photosynthesis) and heterotrophic (organisms obtaining food directly or indirectly from plants). Respiration is described as the process by which food is broken down using oxygen to release energy in cells. There are two types of respiration - aerobic respiration which produces more energy using oxygen, and anaerobic which produces less energy without oxygen. Photosynthesis is defined as the process by which plants make food (carbohydrates) from carbon dioxide and water using sunlight
Life of every organism depends on certain basic processes. Excretion is one among them. Different organisms follow different modes of excretion. In complex organisms including humans, there is a specialized system for excretion called human excretory system.
The document discusses various life processes including nutrition, respiration, and photosynthesis. It provides details on:
1) Nutrition occurs through autotrophic and heterotrophic methods. Autotrophs produce their own food through photosynthesis, while heterotrophs obtain food from other organisms.
2) Respiration is the process by which cells break down food to release energy. It can occur aerobically with oxygen or anaerobically without oxygen.
3) Photosynthesis allows plants to produce food (carbohydrates) from carbon dioxide, water, and sunlight using chlorophyll. Oxygen is released as a byproduct.
This document provides information about nutrition in animals. It begins with an introduction that plants make their own food through photosynthesis while animals obtain food from eating plants or other animals that eat plants.

Rational numbers are numbers that can be expressed as fractions p/q, where q ≠ 0. Rational numbers have several key properties:
Addition, subtraction, and multiplication of rational numbers is closed, meaning the result is also a rational number. Division of rational numbers is not closed as the result can sometimes be an irrational number. The additive and multiplicative identities for rational numbers are 0 and 1 respectively. Rational numbers also follow properties like commutativity, associativity, and distributivity, except for subtraction and division which are not commutative.

3. INTRODUCTION
We use in our daily life a large
number of substances such as lemon,
tamarind, common salt, sugar and
vinegar. Do they have the same
taste? Let us recall tastes of some
edible substances
4. WHAT IS SOUR AND
WHAT IS BITTER ?
Solve the following table :
sour
sugar
sour
sour
sour
sour
neutral
bitter
sour

5. ACIDS
An acid is a chemical substance that has a sour taste.
Many food items such as lemons, curd, vinegar and orange
taste sour because of the presence of acid in them.
Acidic Substances are the substances that contain acid in
them.
Natural Acids are the acids that occur in nature, for example,
acids found in fruits are natural acids
6.
7. BASES
A base is a chemical substance that has a bitter taste and a soapy
texture.
Bases are found in different substances such as bleach, ammonia,
washing powder and soap.
Bases are also called Alkaline.
9. INDICATORS
We cannot taste every object and find its nature. Therefore,
we use indicators.
An indicator is a substance that can determine if another
substance is acidic or basic in nature.
The indicators indicate the presence of an acid or base in a
substance by changing their colour. For Example Turmeric,
China rose petals and Litmus are some natural indicators.
Natural indicators the indicators that occur in nature.
10. LITMUS
Litmus is a natural indicator which
is obtained from Lichens.
Litmus is available in a solution
form and paper strips (red litmus
and blue litmus paper).
It has a mauve (purple) colour in
distilled water. When added to an
acidic solution, it turns red and
when added to a basic solution, it
turns blue. It is available in the
form of a solution, or in the form
of strips on paper, known as
litmus paper.
13. TURMERIC AND
AN INDICATOR
To use turmeric as an indicator
it is generally mixed with water
to form a paste which is then
put on blotting paper and dried
to form thin strips of turmeric
paper.
The turmeric paper is then put
into the solutions in order to
determine their acidity or
alkaline nature.
Sometimes turmeric solution is
also used as an indicator.

15. ACTIVITY 1
You can prepare a card for your mother on her
birthday. Apply turmeric paste on a sheet of plane
white paper and dry it. Draw a beautiful flower with
soap solution with the help of a cotton bud. You will
get a beautiful greeting card.
16. CHINA ROSE AS INDICATOR
China Rose petals are kept in warm water and a coloured solution is obtained from
that. This coloured solution is used as an indicator to test other substances.

19. NUTRELIZATION
Neutralization is a process or a chemical reaction in which an acidic and basic
substance is mixed with each other in order to neutralize their acidic and
alkaline nature.
The product that is formed after the neutralization process is called a Salt.
The salt can have basic, acidic or neutral nature.
The neutralization process results in the generation of heat which raises the
temperature of the reacting mixture.
A synthetic indicator often used for testing neutralization reactions
is Phenolphthalein solution. It is pink in color.
When an acid is added to Phenolphthalein solution, the solution turns colorless,
indicating the presence of an acid.
When a base is added to Phenolphthalein solution, the solution retains its pink
color, indicating the presence of a base.
22. NUTRELIZATION
1. Indigestion
We know that our stomach produces hydrochloric acid which
helps in the digestion of food.
But sometimes the stomach releases too much of acid which
leads to indigestion or sometimes hyperacidity.
Hence, we need to neutralize this acid by taking substances
that are basic in nature commonly known as antacids.
For Example, milk of magnesia is a basic substance that can
neutralize the acid of the stomach.
23.
24. ANT BITE
The irritation of the skin due to ant bite is caused
because of the presence of formic acid that the ant
injects into the skin while biting.
Hence we use a basic substance to neutralize the
effect.
For Example, baking soda or hydrogen carbonate,
calamine solution or zinc carbonate are generally
used to treat ant bites
25. SOIL
TREATMENT
Plants need a soil which is
neutral in nature but using
chemical fertilizers on soil
can turn it into acidic.
To treat acidic soil we use
quicklime (calcium oxide)
or slaked lime (calcium
hydroxide).
Basic soil can be treated by
adding organic substances
to it as they release acids
while decomposing into the
soil.
26. FACTORY WASTES
The factory waste is acidic in nature and cannot be directly
dumped anywhere. Hence bases are added to it before it falls
off into a river or stream so that the aquatic life does not get
affected.
27. EXERCISES
Acids Bases
1. Acids turn blue litmus red. 1. Bases turn red litmus blue.
2. Sour in taste. 2. Bitter in taste.
3. Acids give a dark pink colour with China
Rose indicator.
3. Bases give a dark green colour with
China Rose indicator.
Question1. State differences between acids and bases.
Solution1:
Differences between acids and bases are given below
28. Question2. Ammonia is found in many household products,
such as window cleaners. It turns red litmus blue. What is its
nature?
Solution2:
The nature of the Ammonia is basic.
29. Question3. Name the source from which litmus
solution is obtained. What is the use of this
solution?
Solution3:
Litmus solution is extracted from lichens. It is used as
an indicator to distinguish between bases & acids.
30. Question4. Is the distilled water acidic/basic/neutral? How
would you verify it?
Solution4:
Distilled water is neutral and one can easily test it with the help
of litmus paper. When we dip litmus paper in neutral water,
there will not be any change in the colour.
31. Question5. Describe the process of neutralization with the
help of an example.
Solution5:
When an acid mixed with a base then they react with each
to form the salt with the release of energy and cancel each
other's effect. This process is neutralization process.
Acid + Base → Salt + Water + Heat
Example:
NaOH + HCl → NaCl + H2O + Heat
32. Question6. Mark ‘T’ if the statement is true and ‘F’ if it is
false:
Solution6:
(i) Nitric acid turn red litmus blue. (False)
(ii) Sodium hydroxide turns blue litmus red. (False)
(iii) Sodium hydroxide and hydrochloric acid neutralize each
other and form salt and water. (True)
(iv) Indicator is a substance which shows different colors in
and basic solutions. (True)
(v) Tooth decay is caused by the presence of a base. (False)
33. Question7. Dorji has a few bottles of soft drink in his
restaurant. But, unfortunately, these are not labelled. He has
to serve the drinks on the demand of customers. One
customer wants acidic drink, another wants basic and third
one wants neutral drink. How will Dorji decide which drink is
to be served to whom?
Solution7:
Dorji can use litmus paper to check if the drink is acidic, basic
or neutral and can serve the correct drink as per the
of the customers.
34. Question8. Explain why:
(a) An antacid tablet is taken when you suffer from acidity.
(b) Calamine solution is applied on the skin when an ant bites.
(c) Factory waste is neutralized before disposing it into the water bodies.
Solution8:
(a) Acidity is caused when an excess of acids is produced in the stomach.
An antacid, such as milk of magnesia, act as a base, and react with excess
acid and neutralize its effect, thus giving relief.
(b) When an ant bites it basically injects formic acid into the skin.
Calamine solution contains zinc carbonate and is basic in nature. When
applied in the skin, it reacts with the acid, and neutralizes its effect, thus
giving relief.
(c) Most of the factory wastes contain acids. On disposing it directly into
the water bodies, it might harm aquatic bodies. Hence, factory waste
needed to be neutralized.
35. Question9. Three liquids are given to you. One is hydrochloric acid, another is
sodium hydroxide and third is a sugar solution. How will you identify them? You
have only turmeric indicator.
Solution9:
If we put drops of a base on turmeric, then, the red colour will be obtained. If we
mix acid with turmeric, then, there will not be any change in the colour. Here, on
mixing turmeric indicator with hydrochloric acid, there will not be a change in the
colour. But when we will mix sodium hydroxide, we will get a red colour. The
solution is neutral in nature, so mixing it with turmeric indicator will not cause any
change in colour.
36. Question10. Blue litmus paper is dipped in a
solution. It remains blue. What is the nature of the
solution? Explain.
Solution10:
We know acid turns blue litmus to red and neutral
solution has no effect on the litmus paper. As there
no change in colour, so, the solution can be either
basic or neutral.
37. Question11. Consider the following statements:
(a) Both acids and bases change colour of all indicators.
(b) If an indicator gives a colour change with an acid, it does
not give a change with a base.
(c) If an indicator changes colour with a base, it does not
change colour with an acid.
(d) Change of colour in an acid and a base depends on the
type of the indicator.
Which of these statements are correct?
(i) All four (ii) a and d (iii) b, c and d (iv) only d
Solution11:
(iv) option is correct.
