Reaction Steps
Referring to Equation (9), the potassium persulfate and the sulfuric acid react to form peroxydisulfuric acid and potassium sulfate. In Equation (10), the peroxydisulfuric acid oxidizes the manganese dioxide to form hydrogen permanganate and sulfuric acid. The oxidation of Mn2+ to Mn7+ results in the reformation of MnO4− which is visible by the color change in the bath from purple-brown to purple.
