During electrolytic refining of copper, the anode, the cathode and the electrolyte used respectively are
Options
Impure copper, pure copper, acidified 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.
