Answer 2

Answer:

Using a litmus paper, phenolphthalein, methyl orange, etc. only the acidic or basic character of a solution van be determined, but use of these indicators does not give the idea about the strength of acid or base. so, to get the strength as well as acidic and basic nature of a given solution universal indicator is used. मैं आशा करता हूँ कि आपकों इससे कुछ मदद् मिलेगी।
