Purification of copper can be acheived by electrorefining copper from an impure copper anode onto a pure coppe?
The purification of copper can be achieved by electrorefining, where copper is extracted from an impure copper anode and deposited onto a pure copper cathode in an electrolytic cell. How many hours will it take to deposit 17.0 kg of copper onto the cathode if the current passed through the cell is maintained at 33.5 A? Assume that the copper in the electrolytic solution is present as Cu²⁺.
Hint: Perform a series of conversions to determine the time required to plate out 17.0 kg of copper. The following equations may be useful: 1 mol of electrons (e⁻) = 96,485 C and 1 A·s = 1 C.

1 A = 1 coulomb/sec. Let a coulomb be denoted C. Atomic weight: 63.5
17kgCu x 1000gCu/1kgCu x 1molCu/63.5gCu x 2EqWtCu/1molCu x 96,485C/1EqWtCu x 1sec/33.5C x 1min/60sec x 1hr/60min = 428 hr
