Hi. Okay, I would like to make some sulphuric acid. I know that I can probably find it OTC (and mixed with other potential CRAP), but it's more fun experimenting. I was reading a site which was discussing the preparation of sulphuric acid and it got me excited. So, as far as I know, sulfur is in match head tips. And a bunch of other garbage including phosphorous. SO, can I simply burn a bunch of match heads and pass it through water to form sulphurous acid: SO2 + H2O --> H2SO3 Then, according to this website, heat can be applied (150C) to the solution while being refluxed and... 3H2SO3 ---> 2H2SO4 + H2O + S Which would yield me some pure sulfur in addition to some sulphuric acid, which would be very exciting. So, what do you think? Would it work? Well I guess it WOULD work provided I produce SO2 in my match head burnings. But there has got to be a lot of other stuff in that smoke, but I don't know. If I wanted pure sulphuric acid I could always collect enough of the sulfur that is formed in the reaction and just burn that. Sooo...?
