1. In this experiment, the same potassium permanganate solution that was studied in the previous section is added to the buret. Like the previous experiment, the color change to manganese allows one to detect the equivalence point. MnO4(purple)Mn2+(colorless) In this experiment, the reactant placed in the Erelenmeyer flask is hydrogen peroxide solution. Here is that half reaction: H2O2O2+2H+ Use oxidation numbers to determine if the hydrogen peroxide half reaction represents an oxidation or reduction reaction. Which element undergoes the redox change? (1) I need a hint Oxygen is reduced. Oxygen is oxidized. Hydrogen is oxidized. Hydrogen is reduced
