Answer 1

Universal indicator is an indicator which is widely and mostly used to detect acidic or basic property of a substance.

For example, litmus paper:
Blue litmus turns red in presence of acid and red litmus turns blue in presence of a base.

Methyl orange: Orange colour of it turns pink in presence of an acid and it turns yellow due to a base.
