Hi. I would like to know if sodium bicarbonate electrolysis using lead electrodes could generate lead carbonate, and what would be the reactions
taking place on the cell. Thanks.

Some info on making lead carbonate at bottom here

Don't forget the Lead Salts Preparation thread.

Thanks, i will read.

According to Wikipedia, carbonate ions don’t corrode electrodes so sodium carbonate is actually a better electrolyte than NaCl. Metathesis with
soluble lead salts, particularly nitrate as mentioned, would be your best route.

I feel like either dissolving lead in acetic acid/H2O2 then using a carbonate salt to precipitate it or using a different electrolyte to produce a
soluble lead salt (acetic acid) and precipitate using carbonate is easier. The lead carbonate would probably clump near the the anode and slow down
the electrolysis if you use sodium carbonate as an electrolyte.

Hmm interesting... unfortunately i don't have any lead nitrate or hno3 at the moment, i actually read about this on a amateur chemistry site somewhere
on the internet... i can't remember the source. But anyway, i will try with sodium carbonate and lead electrodes to see what happens.. because this
would be the most viable way for me to do this... anyways thanks for the help so far

What related chemicals do you have access to? Just trying to save you from wasting your time IMO, but by all means if you want to give it a go then
please don’t feel dissuaded, results can always be surprising! Make sure to let us know how it goes, it’s always useful for future reference no
matter whether there’s success or failure.
I’d consider the possibility of generating nitric acid in situ and making the lead carbonate in a one pot reaction. If you have sulphuric acid drain
cleaner and potassium nitrate stump remover of reasonable purity, for instance, these can be added together (with some water of course) to make your
nitric acid. The lead pieces can be dropped in until they’ve dissolved completely, and sodium carbonate solution is then added to drop out the lead
carbonate to be filtered, washed with distilled water, then dried. All the other ions will remain in solution and it means you won’t have to get
your hands on nitric acid - I’m pretty sure the majority of home chemists here make it themselves anyway, me included, due to particularly harsh
restrictions which either make it prohibitively expensive or very difficult to ship.

If you google
surface colouration of stainless steel by oxibe layers
Some hits come up.
One seems good from Rimex metals australia
I cannot up load here at the moment
