Sulfuric acid from copper sulfate

[Gui316]

I've been looking for sulfuric acid. Where I live is quite hard to get it, so I think that I should give it a try to making it. I've seen something about electrolysing a solution of copper sulfate with inert anode and a copper/less reactive metal than copper cathode. Copper ions will be reduced to copper metal, and the water will be split into hydroxide ions, which would be oxidized to oxygen and water at the anode, and we are left with the sulfate and with the hydronium ions, which would combine and form h2so4. Is it really possible? In this case, can I use a 5v 40a power supply for this process? And platinum/iridium alloy as anode?Iridium is quite unreactive, right? WHat about MMO anodes, would it work for this? How can I concentrate the acid? Fractional distillation? Can I distill battery acid as well?

I did this when I was a kid and nobody would give me any sulphuric acid to play with. I used a carbon anode.

Simply boiling the solution will drive off most of the water.

The normal safety remarks about boiling sulphuric acid apply.

carbon floakes too much....is there anyway too make it not to floake?
