Acetic acid is weak acid than sulphuric acid because

Options

(a) it has – COOH group
(b) it decomposes on increasing temperature
(c) it has less degree of ionisation
(d) none of these

Correct Answer:

it has less degree of ionisation

Explanation:

Acetic acid is weak acid than sulphuric acid because it has less degree of ionisation.CH₃COOH + H₂O ⇌ H₃O⁺ + CH₃COO⁻. It has only weak tendency to lose protons. Thus, the equilibrium lies mostly towards the left. However, sulphuric acid is a strong dibasic acid.
