Vedclass · Answer

(C) Electrolytic refining is typically used for metals like $Cu$,$Ag$,$Zn$,etc.,where the metal is deposited from an aqueous solution of its salt. However,$Al$ (Aluminium) cannot be refined by this method because $Al$ is highly reactive and its aqueous salts undergo electrolysis to produce $H_2$ gas at the cathode instead of $Al$ metal. $Al$ is refined by the Hoopes process,which uses a molten electrolyte,not an aqueous solution.

In the electrolytic refining of metals,the electrolysis of an aqueous solution of its complex salt is performed using an impure metal as the anode and a strip of pure metal as the cathode. This method cannot be used for the refining of which of the following metals?
