How many grams of nickel metal are plated out when a constant current of 15.0 A is passed through aqueous NICl2 for 60.0 minutes. Show all work.

Please help!

  • Chemistry 2 -

    Coulombs = A x sec = 15A x 60 min x (60 sec/1 min) = about 54,000 but you need to go through and be more accurate.
    96, coulombs will plate 1 equivalent of Ni. One equivalent is atomic mass/2 = about 58.7/2 = about 29g. Therefore, we can plate out
    29 x (54,000/96,485) = about 16 g.
