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

  • question_answer
    When electricity is passed through the solution of \[AlC{{l}_{3}},\,\,13.5\,\,gm\] of \[Al\] are deposited. The number of Faraday must be [NCERT 1974; MP PET 1992; MP PMT 1994]

    A)                 0.50       

    B)                 1.00

    C)                 1.50       

    D)                 2.00

    Correct Answer: C

    Solution :

               Eq. of Al = \[\frac{13.5}{27/3}=1.5\].                                 Thus 1.5 Faraday is needed.
