Question

How is universal indicator different form an ordinary indicator

Answer 1

A universal indicator is better than an ordinary indicator as it not only shows whether the solution is acidic or basic but also gives the pH values (approx.) by giving a wide range of colours corresponding to different pH values.

Answer 2

Ordinary indicator only identifies weather a given solution is acidic or basic. Whereas an Universal indicator not only identifies the nature of the the solution, but also gives information about the pH of the solution, thus informing about the strength of the acid/base.
