    Which of the following salt when dissolved in water gets hydrolysed?

    A) \[NaCl\]

    B)  \[N{{H}_{4}}Cl\]

    C)  \[KCl\]

    D)  \[N{{a}_{2}}S{{O}_{4}}\]

    Correct Answer: B

    Solution :

     Only salts of strong acid and strong base are not hydrolysed. All other salts can generally hydrolysed. NH4C1 is a salt of weak base and strong add, so it will hydrolyse in water. \[N{{H}_{4}}\xrightarrow{{{H}_{2}}O}\underset{\text{weak}\,\text{base}}{\mathop{N{{H}_{4}}OH}}\,+\underset{\text{strong}\,\text{acid}}{\mathop{HCl}}\,\]
