Solution

The correct option is D

Lead is deposited at the cathode


Electrolysis of Lead Bromide

Lead bromide (PbBr2) undergoes electrolysis to produce lead (Pb) at the cathode and Bromine at the anode. The electrolysis reaction of Lead bromide is,

Cathode:Pb2+Leadion+2e-ā†’PbLeadAnode:Br-Bromideā†’Br+e-

Since Lead is deposited at the cathode during electrolysis of molten lead bromide. Option D is correct.
