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). \[\text{KCl}{{\text{O}}_{\text{4}}}\] a salt of strong acid and strong base, therefore, it does not get hydrolysed in water. \[KCl{{O}_{4}}{{K}^{+}}+ClO_{4}^{-}\]
