First I need to say this is not a formal experiment, Second I'm only here because r/chemistry doesn't let you ask "lab" questions. So here I am.
I came across a denim process online of removing MnO2 stains from fibers using acetic acid, peracetic acid and H202 https://patents.google.com/patent/WO1992013987A1/en
. So I decided to try and remove MnO2 crust off of some MnSiO3 minerals I've collected. I don't have peracetic acid, but I read that mixing H2O2 and acetic acid produces peracetic acid? So I just tried acetic acid 5% and H2O2 3% 1: 1 ratio and It worked really well.
I also tried H2O2 and acetic acid individually as a sort of control, with little to no results. The H2O2 and the Mineral obviously bubbled like crazy because of the MnO2, but the exterior remained covered in MnO2.
All the reactions are just in a jar with a lid placed on top. As to not let in too much O2, but gas can still escape.
I'm just wondering if anybody has an idea what the main products could be? Is the reaction just producing manganese acetate? If so why didn't anything happen in the acetic acid / mineral control? I haven't done chemistry in 10 years, so please go easy on me. Pictures of MnSiO3 mineral before and after.
