Observe the circuit given below

Observe the circuit given below.
Boojho set up this circuit for purification of copper. What will be the nature of
(a) plate A, (b) plate B, © the solution?
Explain the process of purification.


  1. Plate A : Pure copper
  2. Plate B : Impure copper
  3. The solution : Copper sulphate

Copper from impure copper plate is transferred to the pure copper plate by the process of electroplating.
