Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide,H2O2 , can be titrated against a solution of potassium permanganate,KMnO4 . The following equation represents the reaction: 2KMnO2 +H2O2 +3H2SO4----> O2(g) +2MnSO4 + K2SO4 +4H2O(l) A certain amount of hydrogen peroxide was dissolved in 100.mL of water and then titrated with 1.68 M KMnO4. How much HxO2was dissolved if the titration required 19.3mL of the KMnO4 solution?
