Answer 1

$\huge\bold{Answer:-}$

Yes , an acid or base indicator helps in differntiating acids and bases by changing its colour .

For example -

An litmus paper or solution is an acid base indicator that helps us to indicate acids and bases seperately by changing its colour

• An litmus paper or solution changes from red to blue when it react with base.

• An litmus solution pr paper turns blue to red when it reacts with an acid .

Litmus paper is obtained from lichen ( a plant belonging to the division of Thallophyta) . litmus is an natural indicator. litmus solution is actually a purple dye which indicates that the solution is neutral .

Another example u can take is -

Turmeric which is a natural indicator that turns red in basic solutions and remains same in acidic solution .
