Indicate the principle behind the method used for the refining of zinc.

Solution

Zinc is refined using electrolytic refining process. In this process, pure zinc is transported to cathode from the impure sample at the anode. The more basic metal remains in the electrolytic solution and the less basic metals, present as impurities, precipitate as anode mud.

Electrode	Chemical Reaction
Anode	Zn Zn²⁺+2e ^- (From anode)
Cathode	Zn²⁺ 2e^- + Zn (From electrolyte)
