Which of the following cations is not hydrolyzed in aqueous solution ?
(i)$M{g}^{2+}$
(ii)$C{a}^{2+}$
(iii)$N{a}^{+}$
(iv)$K^{+}$

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

Answer 1

Answer: (C)

(i), (ii), (iii), (iv)

Salts of strong acid and strong base are not hydrolysed in aqueous solution. Hence the cations that form strong base are not hydrolysed. According to this, none of the given cations are hydrolysed in aqueous solutions.
