During electrolytic refining of copper, the anode, the cathode and the electrolyte used respectively are

Metals and Non-metals
Extraction of Metals

Options

(A)Impure copper, pure copper, acidified copper sulphate solution
(B)Pure copper, impure copper, sulphuric acid
(C)Pure copper, impure copper, acidified copper sulphate solution
(D)Impure copper, pure copper, distilled water
Official Answer

Impure copper, pure copper, acidified copper sulphate solution

Impure copperPure copperAcidified copper sulphate solution

Hint

Use the process of electrolytic refining to determine the correct answer.

Quick Oral Answer

During electrolytic refining of copper, the anode is made of impure copper, the cathode is made of pure copper, and the electrolyte used is acidified copper sulphate solution.

Analysis & Explanation

During electrolytic refining of copper, the anode is made of impure copper, the cathode is made of pure copper, and the electrolyte used is acidified copper sulphate solution. This is because the impure copper anode is dissolved in the acidified copper sulphate solution, and the pure copper cathode is deposited at the cathode.
