Redox Titration of Hydrogen PeroxideHoa ChungChemistry 1A Spring2016, March 30, 2016Objective/PurposeThe purpose of this experiment is to learn how to determine the concentration of diluteaqueous hydrogen peroxide, H2O2, by titrating it against the standardized potassiumpermanganate, KMnO4, solution.TheoreticalHydrogen peroxide is relatively unstable and decomposes to form water and oxygen gas:H2O2(aq) → H2O(l) + O2(g)In this experiment, we will use the common oxidizing agent potassium permanganate,KMnO4. In acidic solutions, potassium permanganate reacts with hydrogen peroxide according tothe following equation:2MnO4-+ 5H2O2+ 6H+→ 2Mn2++ 5O2+ 8H2OMOSx VOS= MDSx VDSWith VOS= 10 mL, VDS= 100 mLMOS= 10 MDSWhenMOSrefers to the molarity of H2O2original solution.VOSrefers to the volume of H2O2original solution.MDSrefers to the molarity of H2O2diluted solution.
