In Electrolytic refining, the pure metal is used as cathode and impure metal is used as anode. Na 3 AlF 6 is added during electrolysis of Al 2 O 3 to lower the melting point and increase conductivity.

Both Statement I and Statement II are correct

Both Statement I and Statement II are incorrect

Statement I is correct but Statement II is incorrect

Statement I is incorrect but Statement II is correct

In Electrolytic refining, the pure metal is used as cathode and impure metal is used as anode. Na3​AlF6​ is added during electrolysis of Al2​O3​ to lower the melting point and increase conductivity.
