In the electrolytic refining a metal M what would you take as the anode, cathode and electrolyte?

Explanation

In this process, the impure metal is made the anode is a third strip of pure metal is made the cathode. A solution of the metal salt is used as an electrolyte. The apparatus is group as show in figure. On passing the current through electrolyte, the pure metal from the anode dissolves into the electrolyte.

An equivalent amount of pure metal the electrolyte is deposited on the cathode. The so impurities go into the solution, whereas the in solution impurities settle down at the bottom of the anode and known as anode mud.
