Question

Mineral acids are stronger acids than carboxylic acids because :

(i) mineral acids are completely ionized.
(ii) carboxylic acids are completely ionized.
(iii) mineral acids are partially ionized.
(iv) carboxylic acids are partially ionized.

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

Answer 1

Answer: (A)

(i) and (iv)

Carboxylic acid is partially ionized and mineral acid are completely ionized

Carboxylic acids (organic acids) are always weak acids as they are only partly ionized in water. All mineral acids (inorganic acids) are not strong acids. Hydrochloric, nitric, sulphuric, chloric and per chloric acids are common examples of strong mineral acids, and they are completely ionized in water.

hence A is right
