• # question_answer Which of the following salt does not get hydrolysed in water [CPMT 2004] A) $KCl{{O}_{4}}$ B) $N{{H}_{4}}Cl$ C) $C{{H}_{3}}COONa$ D) None of these

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.
