    When during electrolysis of a solution of \[AgN{{O}_{3}},\,\,9650\]coulombs of charge pass through the electroplating bath, the mass of silver deposited on the cathode will be

    A) \[1.08\,\,g\]                                      

    B)        \[10.8\,\,g\]

    C)        \[21.6\,\,g\]                      

    D)        \[108\,\,g\]

    Correct Answer: B

    Solution :

    \[A{{g}^{+}}+{{e}^{-}}\xrightarrow{{}}Ag\] \[9650C=0.1F=0.1\]equivalent\[Ag\]                            \[=0.1\,\,mol\,\,Ag\]                            \[=10.8\,\,g\,\,Ag\]
