A current of 5.61 A is pass through a Ni(NO3)2 solution. How long (in hours) would this current have to be applied to plate out 9.00 g of nickel?

  • Chemistry -

    It takes 95,485 C to plate out 1 gram equivalent of Ni which is 58.7/2 grams or about 30 grams. We want 9.00 grams; therefore,
    96,485 x (9.00/about 30) = Coulombs needed. = estimated 30,000 coulombs.
    Then C = amps x seconds
    You know C and amps, solve for seconds and convert to hours.
