Purification of copper can be achieved by electrorefining copper from an impure copper anode onto a pure copper cathode in an electrolytic cell. How many hours will it take to plate 14.0 kg of copper onto the cathode if the current passed through the cell is held constant at 40.0 A? Assume the copper in the electrolytic solution is present as Cu²⁺.
