Question

Give reason for the following:

Electrolysis of molten lead bromide is considered to be a reaction in which oxidation and reduction go side by side, i.e., a redox reaction.

Electrolysis of molten lead bromide is considered to be a redox reaction. Give reason.

Answer 1

During electrolysis of lead bromide, there is loss of electrons at anode by bromine and gain of electrons at cathode by lead. Thus oxidation and reduction go side by side. Therefore, it is a redox reaction.

\[\ce{PbBr2 <=> Pb^{2+} + 2Br^-}\]
