MCQ
Which of the following is true for electrolytic refining?
  • A
    Pure metal is used at anode and impure metal at cathode.
  • ✓
    Pure metal is used at cathode and impure metal at anode.
  • C
    Both can be possible $A$ and $B.$
  • D
    None of these.
✓

Answer

Correct option: B.
Pure metal is used at cathode and impure metal at anode.
Impure metal will release electron hence form anode electrode and pure metal will absorb electron hence it will be posses as cathode electrode. Pure metal is used as the cathode and impure metal as anode.
