    On passing one faraday of electricity through the electrolytic cells containing \[A{{g}^{+}},N{{i}^{2+}}\] and \[C{{r}^{+3}}\] ions solution, the deposited Ag(At. wt. = 108), Ni (At. wt. = 59) and Cr (At. wt. = 52) is                       

    A) Ag 108gm          Ni 29.5 gm         Cr 17.3 gm

    B) Ag 108 gm    Ni 59.0 gm             Cr 52.0 gm

    C) Ag 108.0 gm  Ni 108.0 gm           Cr 108.0 gm

    D) Ag 108 gm     Ni 117.5 gm           Cr 166.0 gm

    Correct Answer: A

    Solution :

    Wt. of Ag deposited = Eq. wt of Ag = 108 gn Wt. of Ni deposited = Eq. wt of Ni == 29.5 gm. Wt. of Cr deposited = Eq. wt of Cr = 17.3 gm.
