Electrorefining of Metals:
In the electrorefining process, impure metal is purified through electrolysis.
Impure Metal as Anode:
- In electrorefining, the impure metal is attached to the anode.
- The anode undergoes oxidation, where the impurities present in the metal are oxidized and dissolve into the electrolyte.
- This leaves behind a more pure form of the metal at the cathode.
Therefore, the correct statement is:
Option B: Anode and oxidation takes place
