why electolysis of lead bromide is redox reaction
Asked by karthik rao | 22nd Nov, 2013, 04:17: PM
Expert Answer:
The overall reaction can be represented as :
PbBr2 → Pb + Br2
In the electrolysis of lead bromide, reduction takes place at cathode and oxidation takes place at anode so the electrolysis of lead bromide is an redox reaction.
At cathode : Pb+2 + 2e- → Pb( Reduction)
At anode : Br- - e- → Br (Oxidation)
Br + Br → Br2
