The 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 16.5 kg of copper onto the cathode if the current passed through the cell is held constant at 35.0 amperes? Assume the copper in the electrolytic solution is present as Cu2+. (Faraday’s Constant = 96500 Coulombs/mol e–).
