3. Nickel is electrolytically refined at 40°C using an electrolyte containing 50 g/liter of
nickel ion. The anodes contain copper impurities (< 2 wt.%) which may go into solution
as the nickel anode dissolves. Calculate the concentration of Cu2+ ions in solution that
is sufficient to result in the deposition of Cu at the cathode. Given your result, should
one expect to have problems with Cu contamination in the refined Ni?
