Cathode is always taken of pure substance because cathode is for reduction. at anode oxidation takes place and the metal oxidises itself into cation and moves to cathode, and gets deposited there. Whereas the impurities settle down below anode as anode mud.

Electrolysis of Impure Copper with Zinc Impurity
Explanation:
Impure Copper as Anode:
- In the process of refining impure copper with zinc impurity, the impure copper is used as the anode.
- This is because during electrolysis, the impure copper will lose electrons at the anode and oxidize to form copper ions in the solution.
Pure Copper as Cathode:
- On the other hand, pure copper is used as the cathode in the electrolysis process.
- The pure copper cathode will attract the copper ions present in the solution and facilitate the deposition of pure copper onto the cathode.
Electrolysis Setup:
- The setup of electrolysis involves the impure copper as the anode and pure copper as the cathode.
- When an electric current is passed through the electrolyte solution, copper ions from the impure copper anode will move towards the cathode and get deposited, thus refining the impure copper.
Conclusion:
- Therefore, the correct electrodes to be used in the electrolysis of impure copper with zinc impurity are pure copper as the cathode and impure copper as the anode.
