    Which of the following salts when dissolved in  water hydrolyse?

    A)  \[NaCl\]                             

    B)  \[N{{H}_{4}}Cl\]

    C)  \[KCl\]                                

    D)  \[N{{a}_{2}}S{{O}_{4}}\]

    Correct Answer: B

    Solution :

    \[N{{H}_{4}}Cl\]is a salt of strong acid and weak base. The solution of \[N{{H}_{4}}Cl\] show acidic character on hydrolysis. \[N{{H}_{4}}Cl+{{H}_{2}}O\rightleftharpoons \underset{\begin{smallmatrix}  weak \\  base \end{smallmatrix}}{\mathop{N{{H}_{4}}OH}}\,+\underset{\begin{smallmatrix}  strong \\  acid \end{smallmatrix}}{\mathop{HCl}}\,\]
