Lab Procedure

[budullewraagh]

i was thinking of making some H2SO4 using the following procedure;

 

electrolysis; MgSO4 solution, Al cathode, Cu anode ->CuSO4

of course, some of the CuSO4 is actually Cu(OH)2 and H2SO4. my question is how can i get the reverse acid base reaction to be favored?

Shift the equilibrium through pH?pOH?

Why do you want to do it this way, it seems awfully harder than say jsut buying some

[budullewraagh]

i've tried buying it; it's nowhere. explain your proposal

[Crash]

What country do you live in?, how old are you?

i really dont want to work with SO2; it's quite toxic and i dont have the resources to work with...i dont have vanadium...plus, if you read the synthesis, you need H2SO4 to make H2SO4. i've seen that synthesis, but it doesnt work for me since i dont have the resources.

Ok

S8 + O2 --> SO2

SO2 + O2 <-- --> SO3 (exothermic, SO2 side is favoured!)

SO3 + H2O --> H2SO4 (extremely dangerous fog! must take EXTREME caution)

 

You only need Sulfuric acid to turn your new sulfuric acid into oleum (H2S2O7) to be safely transoprted

you need a catalyst for that reaction. i forgot what it is but i won't be able to find it. thanks though.

Take battery acid? It's H2SO4 not to conc. but would work if you got nothing else just a thought use it, don't use it.
