A word on the original topic.....
When using lead electrodes in Na Cl solution one
would get the rather unsoluble PbCl2 on anode and it passivates the surface.
There's no way to oxidize Cl- ions on lead so no free chlorine, chorite or chlorate ions will form in this case.
Electrons are drawn from lead metal instead of Cl- ions and that leaves only one option- PbCl2
Pb(OH)will precipitate on cathode and it will corrode accordingly....
