Question

write any 2 difference between "common acid-base indicators and universal indicators".

if you know then only answer. ​

Answer 1

Explanation:

A chemical indicator is a substance that can show a change of a measurable parameter in response to a change in the solution. The change should be observable such as a color change, temperature change, precipitate formation, etc. The substances that cause a color change in response to the pH of the medium are called acid-base indicators because these substances are used to identify the termination of an acid-base reaction. Indicators show different colors at different pH values. The term universal indicator is used to name a chemical compound that can act as an indicator for a wide range of pH values. The main difference between acid base indicator and universal indicator is that acid base indicators show color changes at a certain pH range whereas universal indicators show color changes at a wide variety of pH values ranging from 0 to 14.
