I made some sulfuric acid using the sulfur dioxide/oxidiser method using concentrated hyrogen peroxide and am planning on using in a synthesis where
leftover peroxide would not be ideal (peroxides and organics, you know, the friendly combination). I am fairly certain all of it will react but I cant
be certain. What catalysts could I use to decompose any remaining peroxide quickly that wouldn't react with the acid?fusso - 19-4-2019 at 19:21
Formaldehyde/formic acid?
Edit: maybe just any organics? Trace H2O2 in H2SO4 is just like a very weak piranha soln.

Maybe just heating the acid to its boiling point is enough? At high temperatures H2O2 isn't stable and as a plus you will also make the acid water

Just heat it up you crazy bastards, H2SO5 decomposes at elevated temperature.
100*C is more than adequate and i suspect you will want to boil it down to remove water anyway.Ubya - 20-4-2019 at 05:07

Easiest and fastest way, it's not even needed to BOIL sulphuric acid, so less riskCharlieA - 20-4-2019 at 17:41
ditto to Ubya, even if he ignored Assumed Fish's poor choice of words..
