During the electrolysis of molten lead bromide which of the following takes place? (A) Bromine is released at the cathode (B) Lead is deposited at the anode (C) Bromine ions gain electrons (D) Lead is deposited at the cathode

Lead is deposited at the cathode

During the electrolysis of molten Lead bromide,

At anode

[latex]2Br^{-}\rightarrow Br_{2}[/latex]

At cathode

[latex]Pb^{+2}+2e^{-}\rightarrow Pb[/latex]

Therefore, lead is deposited at cathode

So, the correct option is (D)
