How copper is refined by electrolytic method?

Text Solution

Verified by Experts

Impure copper is made as anode and thin sheet of pure copper is made as cathode. Acidified copper sulphate solution is taken as electrolyte.
On passing electric current, pure copper deposits on the cathode.
At anode : `CurarrCu^(2+)+2e^(-)`
At cathode : `Cu^(2+)+2e^(-)rarrCu`
