Question

Mineral acids are stronger acids than carboxylic acids because:
(i) Mineral acids are completely ionised in aq. solution.
(ii) Carboxylic acids are completely ionised in aq. solution.
(iii) Mineral acids are partially ionised in aq. solution.
(iv) Carboxylic acids are partially ionised in aq. solution.

• A. (i) and (iv)
• B. (ii) and (iii)
• C. (i) and (ii)
• D. (iii) and (iv)

Answer 1

The correct option is A (i) and (iv)

Carboxylic acids, when added to water, ionize partially and hence are weak acids. Mineral acids, when added to water, ionize completely and hence are strong acids.
