In electro-refining, the pure metal is deposited on

A. Vessel

B. Electrolyte

C. Cathode

D. Anode

Answer: Option C

Solution(By Examveda Team)

In electro-refining, the anodes consist of unrefined impure metal, and as the current passes through the acidic electrolyte the anodes are corroded into the solution so that the electroplating process deposits refined pure metal onto the cathodes. Electrolytic refining is used to extract impurities from crude metals.
