Which one of the following Figures correctly describes the process of electrolytic refining? 

Options

A.
B.
C.
D.

Answer

c

Explanation

For the process of electrolytic refining, impure metal is made anode and is connected to the positive terminal of battery. Pure metal is made cathode and is connected to the negative terminal of the battery.
`Cu^(2+)` ions from the soiution are deposited on the cathode while Cu from impure anode dissolves into the soiution and the impurities settle down below anode as anode mud.
