    \[N{{H}_{4}}Cl\]solution is :

    A) neutral                                

    B) acidic

    C) basic                                     

    D) amphoteric

    Correct Answer: B

    Solution :

    \[\text{N}{{\text{H}}_{\text{4}}}\text{Cl}\]is a salt of strong acid and weak base \[\text{N}{{\text{H}}_{\text{4}}}\text{Cl}\]in water is hydrolysed as follows \[\text{N}{{\text{H}}_{4}}Cl+HOH\xrightarrow{{}}\underset{weak\,base}{\mathop{N{{H}_{4}}OH+}}\,\underset{strong\,\,acid}{\mathop{{{H}^{+}}}}\,+C{{l}^{-}}\] \[\text{HCl}\]being strong acid remain ionized completely. Hence, the solution is acidic
