Question

Acetic acid is weak acid than sulphuric acid because:

• A. It has $-\mathrm{COOH}$ group
• B. It has higher degree of ionization
• C. It has lesser degree of ionisation
• D. It decomposes on increasing temperature

Answer 1

The correct option is C

It has lesser degree of ionisation

Explanation:

• Sulfuric acid (H₂SO₄) is a strong acid as it ionizes to a greater extent.
• Acetic acid (CH₃COOH) is a weak acid as it ionizes to a smaller extent.
• Acetic acid is weak acid than sulfuric acid because it has a lesser degree of ionization.

Therefore, the correct option is (C)
