In the process of Electrorefining of Copper shown in the diagram below, which of the following statements is correct?

- (a)The anode is made of pure Copper.
- (b)The cathode is made of impure Copper.
- (c)Copper is deposited at the anode.
- (d)Copper ions from the anode move to the cathode and get deposited as pure Copper.

Copper ions from the anode move to the cathode and get deposited as pure Copper.
Reason — At the anode, impure copper dissolves into the solution as Cu2+ ions. These Cu2+ ions migrate through the solution to the cathode, where they gain electrons and are deposited as pure copper.
