MCQ
Which of the following is true for electrolytic refining?
- APure metal is used at anode and impure metal at cathode.
- ✓Pure metal is used at cathode and impure metal at anode.
- CBoth can be possible $A$ and $B.$
- DNone 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.
