Sodium Peroxoborate reacts with sulfuric acid and potassium permanganate to give what products?
2MnO4- + 5H2O2 + 6H+ → 2Mn2+ + 5O2 + 8H2O
Permanganate is added to H2SO4 + H2O2 and is reduced because it
is a better oxidising agent that H2O2
the purple MnO4 ion is used up and the solution fades almost to
clear if the mix is right
