    In dry cell the reaction which takes place at the zinc anode is [MP PET 1996]

    A)                 \[Z{{n}^{2+}}+2{{e}^{-}}\to Zn(s)\]

    B)                 \[Zn(s)\to Z{{n}^{2+}}+2{{e}^{-}}\]

    C)                 \[M{{n}^{2+}}+2{{e}^{-}}\to Mn(s)\]

    D)                 \[Mn(s)\to M{{n}^{+}}+{{e}^{-}}+1.5V\]

    Correct Answer: B

    Solution :

                    At anode: \[Z{{n}_{(s)}}\to Z{{n}^{2+}}+2{{e}^{-}}\].
