Question

Observe the circuit given in Fig. 14.8.

Boojho set up this circuit for purification of copper. What will be the nature of – (i) plate A (ii) plate B (iii) the solution. 

Explain the process of purification.

Answer 1

(i) plate A –                Pure copper

(ii) plate B –               Impure copper

(iii) the solution –      Copper sulphate

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