During electrolytic refining of zinc, it-

Correct option is C

The correct answer is (c) Gets deposited on cathode.
· In the electrolytic refining process of zinc, the pure metal is deposited on the cathode.
· Zinc ore or impure zinc acts as the anode, while a pure zinc plate serves as the cathode.
· An electrolyte solution of zinc sulfate ( ZnSO₄) is used, often mixed with sulfuric acid to improve conductivity.
· When an electric current passes through the electrolyte, zinc ions ( Zn²⁺) from the anode move towards the cathode.
· At the cathode, these zinc ions gain electrons ( reduction) and get deposited as pure zinc.
· The impurities present in the anode do not deposit at the cathode but either fall off as anode mud or remain dissolved in the electrolyte.
Additional Knowledge:
· Gets deposited on anode: This is incorrect, as the anode dissolves, releasing zinc ions into the solution.
· Gets deposited on cathode as well as anode: Incorrect, as zinc only deposits at the cathode. The anode dissolves during the process.
· Remains in the solution: Incorrect, since zinc ions in the solution migrate to the cathode where they are deposited as solid zinc.
