Answer 2

Answer:

Cathode is a thin strip of impure copper.

Explanation:

Electroplating of copper : It is a chemical process in which pure copper is obtained from impure copper using electrolysis. Impure copper is anode and the electrolyte is copper sulphate solution.

When electricity is passed through it, a chemical reaction starts. Impure copper anode is dissolved and releases copper which gets deposited on the cathode. Due to the deposition of impure copper on anode, it gets thicker.
