Re: [DIYbio] What happens when you electrolyse sodium bicarb solution?

It's not always available: I have yet to find sulphuric acid available
for sale around Ireland, although HCl is available as 10M solution in
hardware stores.

That said, electrolysing etc. to make hard Sulphuric acid might be a
waste of effort if all you need is a strong mineral acid: use HCl
instead. But if it's gotta be sulphuric, it might not be available locally..
