JEE Main & Advanced Chemistry Electrochemistry / विद्युत् रसायन Question Bank Faraday's law of electrolysis

  • question_answer
    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                [AIIMS 1982]

    A)                 \[Ag\]                   \[Ni\]                    \[Cr\]                 108 gm                29.5 gm                17.3 gm

    B)                 108 gm 59.0 gm                52.0 gm

    C)                 108.0 gm              108.0 gm              108.0 gm

    D)                 108 gm                 117.5 gm              166.0 gm

    Correct Answer: A

    Solution :

               \[\text{Wt}\text{.}\,\text{of}\,Ag\,\text{deposited}=Eq.\,wt\,of\,Ag=108\,gm\] \[\text{Wt}\text{.}\,\text{of}\,Ni\,\text{deposited}=Eq.\,wt.\,of\,Ni=29.5\,gm\] \[\text{Wt}.\,of\,Cr\,\text{deposited}=Eq.\,wt.\,of\,Cr=17.3\,gm\].
