When the sample of Cu with Zn as impurity is to be purified by electrolysis, the appropriate electrodes are :

A

`{:("Cathode","Anode"),("Pure Zn","Pure Cu"):}`

B

`{:("Cathode","Anode"),("Impure sample","Pure Cu"):}`

C

`{:("Cathode","Anode"),("Impure Zn","Impure sample"):}`

D

`{:("Cathode","Anode"),("Pure Cu","Impure sample"):}`

Text Solution

Verified by Experts

The correct Answer is:
D

Pure Cu acts as cathode while impure sample is in the form of anode.
