1. Into a 250-mL beaker, use a pipette to precisely add 10.00 mL of the hydrogen peroxide, H2O2, solution. 2. Next, use a pipette to add 1.0 ml of 3M H2SO4, sulfuric acid, and 0.5 mL of conc. H3PO4, phosphoric acid to the peroxide solution. 3. Titrate the peroxide solution with the MnO4", permanganate, solution. (Very slowly and carefully add the permanganate to the peroxide until a color change is observed. You must stop the addition at just the instance that the color change is observed otherwise you will have passed the stoichiometric endpoint and you will have an excess of permanganate.) 5.33ml 36.75ML Initial volume of MnO4- in the burette Final volume of MnO4- in the burette Volume of MnO4- added
