Question

What are acid base indicators

Answer 1

A substances such as litmus paper that indicates the degree of acidity or basicity of a solution through characteristic color change

Answer 2

• What is Acid-Base Indicator?

Acid-Base Indicator is a Chemical Substance or determinant which determines whether a compound/element/mixture is acidic in nature or it is basic.

• ACIDS, BASES AND SALTS

• Acid are the substances which gives H⁺ (Hydrogen/Hydronium Ion) ion while they disassociate in water.

They are corrosive as well as sour in taste. They turns Blue Litmus Red.

*Litmus is also an indicator obtained from Lichens.

pH of such substance lies in [1,7)

• Base are the Substances which gives OH⁻ (Hydroxide) ion while it disassociate in water.

These are also corrosive and bitter in taste which turns red litmus to blue.

pH of such substance lies between (7,14]

• Salts are the substances which are formed due to the reaction between an acid and a base known as Neutralisation reaction.
