Unfortunately nobody can claim to be the Best Chemist Ever, nor can quick experiments show the Full story.

Sn has a horrible tendency to form metastannic acid under those conditions, given Time.

It's like snot.

I also want to separate these metals. Is it a viable option to dissolve it in nitric acid which would create solution of lead nitrate and SnO2? How would I go about reducing SnO2 to Sn metal (besides reduction with charcoal)?


electrochemicaly be easiest method,

How would I do that with this insoluble compound?


look at codies lab video it works very well the lead gunk then can be melted and used for what ever or tin for what ever, Tin will be useless for me but I'll make lead acetate via 35%H2O2 and glacial acetic acid

@Akhil:

SnCl4 could probably present in soln so it didnt ppt out.

Well that's good for this separation because it means we have lead in solution and tin as a precipitate. But the question about reducing it to Sn metal still remains (besides using charcoal as that has a tendency to dissolve in molten metal, thus making impure tin).
