Does anybody know how to make sulphic acid out of organic compound readably available .

 

more info

A friend of mine did it and challenge me to see if i can do it.

I am pretty sure it was some fluid from some insect but i have no idea.

sulphic acid doesn't exist.

 

sulphuric acid does, but making it is very dangerous.

Formic acid also exists and it can be made from insects.

It's also rather more dangerous than most people expect- it burns skin rather better than conc HCl does.

Sorry my English is bad , i thought it was something like nitric acid .

 

Still can it be obtained from some biological organisms.

do you perhaps mean sulphurous acid?
