Question

How will you refine copper? Give a labelled diagram of the electrolytic cell used for the refining of the copper

Answer 1

In the electrolytic refining of copper, the impure metal is made the anode and a thin strip of pure metal is made the cathode, a solution of the metal salt is used as an electrolyte. on passing the current through theelectrolyte,the pure metal from the anode dissolves into the electrolyte.

Answer 2

Copper is refined by the process of electrolysis in which there is a cathode, anode and an electrolytic solution.

The impurities move from one node to the other and thus we obtain copper which is 99.99 % pure.

This level of purity is necessary when using copper for making of conducting wires.
