MCQ
In electro-refining, thick sheets of pure copper are obtained at:
- ✓Cathode.
- BAnode.
- CElectrode.
- DNone of the above.
✓
Answer
Correct option: A.
Cathode.
In the electrolysis of copper, pure copper gets deposited on the cathode while impure copper at the anode goes to the solution. So, the cathode increases in thickness.
