  • question_answer
    On passing 96500 coulomb of charge through a solution \[CuS{{O}_{4}}\] the amount of copper liberated is         [MP PMT 2001]

    A)                    64 gm                              

    B)                    32 gm

    C)                    32 kg                                

    D)                    64 kg

    Correct Answer: B

    Solution :

                       1 faraday (96500C) is the electricity which liberated that amount of substance which is equal to equivalent wt. So liberated amount of \[Cu\] is \[\frac{63.5}{2}\] \[=31.25\,gm\approx 32\,gm\]
