Hydrogen Peroxide Analysis In acid solution, the dark purple MnO 4-oxidizes hydrogen peroxide, forming oxygen gas and very pale pink Mn2+ ions. Thus, when a solution of KMnO 4 is added dropwise to an acidified solution of hydrogen peroxide, each drop is decolorized until all the H 2O 2 is used up. The next drop of
