Question

Write equations for the reactions taking place at the two electrodes (mentioning clearly the name of the electrode) during the electrolysis of Molten lead bromide with inert electrodes

Answer 1

The cathode and anode are both made of graphite plates.

Reaction at the cathode: `Pb^(2+) + 2e^(-) -> Pb`

Reaction at the anode: `Br^(-) - e^(-) -> Br`

                              `Br  + Br ->  Br_2`
