    The chemical equivalent of silver is 108. If the current in a silver voltameter is 2 Amp., the time required to deposit 27 grams of silver will be                                             [MP PMT 2004]

    A)                    8.57 hrs                           

    B)                    6.70 hrs

    C)                    3.35 hrs                           

    D)                    12.50 hrs

    Correct Answer: C

    Solution :

                       m = Zi t Þ \[t=\frac{m}{Zi}=\frac{m\times F}{E\times i}\]    \[\left( \because \,Z=\frac{E}{F} \right)\] \[t=\frac{27\times 96500}{108\times 2}=12062.5\,\sec \]\[=\frac{12062.5}{3600}hr=3.35\,hr\]
