For corrosion resistance, a steel bolt is plated with nickel from a solution of nickel(II)sulfate. If 0.250 g of nickel produces a plating of the required thickness and a current of 0.540 A is used, predict how long in minutes the process will take

  • chemistry -

    amperes x seconds = coulombs
    96,485 coulombs will plate 1 equivalent weight Ni.
    1 equivalent weight Ni = atomic mass/change in # electrons for the Ni half cell.
