Solution
Electrolytic refining:-
It is a method used for the extraction and purification of impure metals through the process of electrolysis.
In this method, crude metal is used as the anode, and a strip of pure metal is used as the cathode and the soluble salt of the same metal is used as the electrolyte.
When an electric current is transmitted, metal ions from the electrolyte are deposited as a pure metal in the cathode, and the impure metal from the anode dissolves in the form of ions into the electrolyte.
Below the anode, the impurities of metals are collected, and it is known as the anode mud.
Therefore, in electrolytic refining, the impure metal is made asanode.
