Answer:

Acid - Base indicators (also known as pH indicators) are substances which change colour with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions. Consider an indicator which is a weak acid, with the formula HIn.

An acid turns blue litmus paper red. A base turns red litmus paper blue. ... Substances which change their smell when mixed with acid or base are known as olfactory indicators. For example onion, vanilla, clove, etc.
