Copper is to be deposited from a solution that is 0.250 M in Cu(II) and is buffered to a pH of 4.00. Oxygen is evolved from the anode at a partial pressure of 730 torr. The cell has a resistance of 3.60 V, and the temperature is 25°C. Calculate
(a) The theoretical potential needed to initiate deposition of copper from this solution.
(b) The IR drop associated with a current of 0.15 A in this cell.
(c) The initial potential, given that the overvoltage of oxygen is 0.50 V under these conditions.
(d) The potential of the cell when [Cu2+] is 7.00 ( 10-6, assuming that IR drop and O2 overvoltage remain unchanged.
