As you need Staff Selection Commission Combined Graduate Level Examination SSC CGL exam Chemistry notes, here I am giving:

ACIDS AND BASES


Curd, lemon juice, orange juice and vinegar taste sour. These substances taste sour because they contain acids.
The chemical nature of such substances is acidic.
The word acid comes from the Latin word acere which means sour.
The acids in these substances are natural acids

Substances like these which are bitter in taste and feel soapy on touching are known as bases.

The nature of such substances is said to be basic.

Special type of substances are used to test whether a substance is acidic or basic. These substances are known as indicators

Indicators

The indicators change their colour when added to a solution containing an acidic or a basic substance. Turmeric, litmus, china rose petals (Gudhal), etc., are some of the naturally occurring indicators.

NATURAL INDICATORS AROUND US

Litmus: A natural dye

Turmeric is another natural indicator
Why a turmeric stain on my white shirt is turned to red when it is washed with soap. It is because the soap solution is basic

To prepare limewater, dissolve some lime (chuna) in water in a bottle. Stir the solution and keep it for some time. Pour a little from the top. This is lime water.
