    A silver and zinc voltameter are connected in series and a current i is passed through them for a time t liberating W gm of zinc. The weight of silver deposited is nearly  [NCERT 1973, 76]

    A)                    W                                      

    B)                    1.7 W

    C)                    2.4 W                               

    D)                    3.5 W

    Correct Answer: D

    Solution :

                       \[\frac{{{m}_{Zn}}}{{{m}_{Ag}}}=\frac{{{E}_{Zn}}}{{{E}_{Ag}}}\] Þ \[{{m}_{Ag}}=W\,\left( \frac{{{E}_{Ag}}}{{{E}_{Zn}}} \right)\]= 3.3 W = 3.5 W
