Explanation:

(i) At the anode oxidation reaction takes place.

At anode : Cu−2e

→Cu

2+

At cathode redution reaction occurs.

At cathode : Cu

2+

+2e

→Cu

Here both copper electrodes are used.

(ii) At anode : Br

−e

→Br

Br+Br→Br

2

At cathode : Pb

2+

+2e

→Pb

Here both anode and cathode are made up of graphite as it is unaffected by bromine vapours.
