Please help me with this question's solution
Copper is purified upto 99.95% purity using electrolytic refining method. An electrolytic cell is prepared to do this refining .Diagram shown below is an electrolytic cell used for copper refining.
In such a cell a thin sheet of high-purity Cu serves as the cathode, and the anode is the impure Cu which is to be refined. The electrolyte is a solution of copper(II)sulfate. When current is passed in system the Cu+ moves towards the cathode where it gains electron and turn as metallic Cu. At anode impure copper release electrons go into solution as Cu2+.
At the cathode,
At the anode,
In this way pure copper is obtained as cathod rod at the end of the process.
Hence, the correct option is (c).
