Question

what differenitate between strong and weak acid . Identify the strong and weak acid from the following list of acids. hydrochloric acid, acitic acid, formic acid, nitric acid?​

Answer 1

Strong acids are those whose degree of ionization is more than 30% and whose solutions contain more ions than molecules. Weak acids are those whose degree of ionization is less than 30%. All organic acids are weak acids.

Hydrochloric acid and Nitric acid-strong as their degree of ionization is more than 97%

Acetic and formic acids-weak as they are organic acids

Answer 2

by using litmus paper and match the colour of litmus paper of each acid according to the pH paper
