Answer» Principle - On passing electric current pure metal collected at cathode. Method - Thick plate of impure metal is taken as anode and thin plate of pure metal is taken as cathode. Electrolyte is an aqueous salt solution of metal. On passing electric current pure metal is collected at cathode and impurities settle down as anode mud. Reaction at anode M → Mn+ + ne- Reaction at cathode Mn+ + ne- → M |
