another route to diy Sulphuric acid ?
In the Wikipedia article on manganese dioxide
https://en.m.wikipedia.org/wiki/Manganese_dioxide
under "Production" I found this:
2 KMnO4 + 3 MnSO4 + 2 H2O→ 5 MnO2 + K2SO4 + 2 H2SO4
"the action of potassium permanganate over manganese sulfate crystals produces the desired oxide."
Not cheap, but available
Workable ?

Intresting. I'm not at my lab ,why not test it and record the pH if this works then we can confirm.

Water is dangerous if you don't know how to handle it, elemental fluorine (F₂) on the other hand is pretty tame if you know what you are doing.

This is interesting, but Wikipedia focuses on the desired product in writing the reaction formulae and doesn't really address balancing the side
products. It should be:
2 KMnO4 + 3 MnSO4 + 2 H2O >> 5 MnO2 + 2 KHSO4 + H2SO4
Now you need to separate the formed H2SO4 from the potassium bisulfate byproduct. This is the same problem that occurs with the ethanol method. In
fact, ethanol would probably be my first guess for the separation here, since it will promote disproportionation of the bisulfate.
I guess it's still useful if you can't buy potassium bisulfate.
