1.Measure out precisely 10 mL of 0.3% hydrogen peroxide solution from the dispensing burette your teacher has prepared into a 250 mL Erlenmeyer Flask. Should you miss the 10.00 mL mark, just record the volume of your sample exactly.2.Measure out approximately 10 M of 4.5Msulfuric acid, H2SO4, solution from dispensing burette your teacher has prepared into the flask containg the 0.3% hydrogen peroxide solution. Caution:H2SO4is a strong acid, and should be handled with care.3.Use a graduated cylinder to meaure out approximately 25 mL of water and add it to the beaker as well.4.Set up a ring stand, a burette clamp, and a burette to conduct the titration. Rinse and fill the 50 Ml burette with 0.0200 M MnO4-solution. CAUTION: Handle the KMnOsolution with care; it has been mixed the H2SO4 which can cause painful burns if it comes in contact with the skin. 4 Equations: 5H202 + @MnO4 + 6H – 5O2 + 2Mn + 8H2O Ox: Mno4 + 8H + 5e- Mn + 4H2O Red: H2O2 – 2H + O2 + 2e Graphs: Insufficient data Post-Lab Questions:
