Problem- Purification of nickel can be achieved by electrorefining nickel from an impure nickel anode onto a pure nickel cathode in an electrolytic cell. How many hours will it take to plate 14.0 kg of nickel onto the cathode if the current passed through the cell is held constant at 44.5 A? Assume the nickel in the electrolytic solution is present as Ni^2+.
