Synthesis of Sulphuric acid through Oxalic acid and Sulphur.

[AronN3]

Instead of CuSO₄ if we use Sulphur in H₂C₂O₄ the reaction as follows,

H₂C₂O₄ + S = H₂SO₄ + CO₂ + H₂S(😶‍🌫️) 

or it can follow 

H₂C₂O₄ + S = SO₂ + CO₂ +H₂O ^{(sealed reaction)} 

so that Sulphir dioxide can react with the water 🤔  .

Just hate CuC₂O₄  precipitation too much effort. 🤕

From SO2 only get H2SO3 sulfurous acid. Not H2SO4  sulfuric acid.

This you can have easier, if you burn sulfur.

S + O2 => SO2

 

For Sulfuric acid you need a catalyst to oxidise SO2 to SO3.

I can do that same with this reaction by using H₂O_{2  i} instead of water. But i was looking for a more easy and direct approach. Copper sulphate does better in this case. However its a disaster for cleanup as like as burning sulphur, that's why I was looking for an alternative . The first reaction is very convenient since the byproducts are only gases. But later I thought second reactions might also occur so I need some advises from experts 🥙🤠.  

I used to make it by distilling battery acid (35%) but it is now replaced with electrolyte gel . Really puzzled 🫥 cant get to Ti-Pt electrodes not even MMO(or leadO2 and to make PbO2 i need sulphuric acid) for electrolysis. And using graphite is wasting time since it will look like I am producing graphite powder instead of Sulphuric acid😅 there's  another way for anode is to use Sn-Pb soldering iron 😬 but i haven't tried it unsure whether it will work (a deep grudge against PbSO4). 

 

So that's why i was just hoping to find a direct approach for making it. 😮‍💨
