    I have already posted this on mechanical, structural and chemical engineering but I kinda want a quick answer. I was pondering making a domestic hydrogen power generator and the only way to make a safe concentration of hydrogen that is achievable by me is through electrolysis via the hofmann voltameter, but I can't find a glass one big enough. So I was wondering, can I make a hofmann voltameter with PVC pipes.

    I don't see why not, so long as the chemical you use to make water conductive won't react with the pvc.

    I'm pretty sure that'll be OK

    Since the water just has to conduct a small amount, you won't need a large molarity of sulfuric acid. I wouldn't worry about the fact that it's pvc. Obviously it won't be labratory grade, but if you're just doing it for your own purposes, it should be fine.
