sulfuric acid from sulfur flour

[woo-jong]

I wonder whether my theory is correct or not

My theory :

S+O2 --------> SO2

when sulfur burns(reacts with oxygen), sulfur dioxide is formed

and this gas dissolves in water and makes sulfurous acid

SO2+H2O ------> H2SO3

sulfurous acid is decomposed by electrolysis

H2SO3 ---electrolysis---> H2↑+SO3

sulfur trioxide makes sulfuric acid with water.

SO3+H2O ------> H2SO4

is my theory correct? if there is some mistake, please tell me about my mistake. and I maybe have some mistake in my English ,too because I'm Korean person

I don't think electolyse of sulfurous acid would yield sulfuric acid.

you could try to burn sulfur and then convert the SO2 created too SO3 via an catalyst like iron oxide or platinum. you should apply strong heat too the catalyst and then lead the SO3 into water.

I think this may have been discussed before but im not sure. This thread is in the wrong section and you double posted. <img border="0" title="" alt="[Eek!]" src="eek.gif" />

Either figure out how we operate around here or you'll get banned. :mad:

Im hoping something good will come out f this thread so im not going to close it.

Moving to chemistry related.
