During electrolytic refining of zinc, it gets
(a) deposited on cathode
(b) deposited on anode
(c) deposited on cathode as well as anode
(d) remains in the solution
Ans. (a)
Electrolytic refining is a process of refining a metal by the process of electrolysis.
The impure metal is made the anode and a thin strip of pure metal is made the cathode.
The pure zinc metal deposited on cathode is connected to the negative terminal of the battery.
Zn2+ ions from the solution move towards the negatively charged cathode.
Hence, Zn is deposited on the cathode.
Therefore option (a) is correct
