Which of the following salt does not get hydrolysed in water?

A) \[KCl{{O}_{4}}\]                               

B) \[N{{H}_{4}}Cl\]

C) \[C{{H}_{3}}COONa\]    

D)  None of these

Correct Answer: A

Solution :

                 Only salts of (weak acid + strong base) and (strong acid + weak base) get hydrolysed (i.e., show alkalinity or acidity in water).\[KCl{{O}_{4}}\]is a salt of strong acid and strong base, therefore it does not get hydrolysed in water. \[KCl{{O}_{4}}{{K}^{+}}+ClO_{4}^{-}\]
