Hi.
I made some time ago solution of ammonium-ferric sulfate from ferrous sulfate, amonia, sulfuric acid and hydrogen peroxide. I used originally 10% H2O2
but this is not enough strong and have much water, so I bought 30% H2O2 and try it with it. I add slowly peroxide into the solution but peroxide
rapdly decomposes even in room temperature and I breathed some of the irritating aerosol from it. Is there any health risk from it?
Solution sadly isn't completly oxidize. If I added small amount of it into NaOH, it is still form little bit of green precipitate (with brown
precipitate) and permanganate test is positive. Any ideas?
