    In the electrolysis of dilute £[2804 using platinum electrode

    A) \[{{\text{H}}_{\text{2}}}\]is liberated at cathode

    B) \[{{\text{O}}_{\text{2}}}\]is produced at cathode

    C) \[\text{C}{{\text{l}}_{\text{2}}}\] is obtained at cathode

    D) \[\text{N}{{\text{H}}_{\text{3}}}\] is produced at anode

    Correct Answer: A

    Solution :

     \[{{\text{H}}_{\text{2}}}\]is tibrated at cathode and\[{{\text{O}}_{\text{2}}}\] is liberated at anode. \[2{{H}^{+}}+2{{e}^{-}}\xrightarrow{{}}{{H}_{2}}\]
