Redox titrations are used to determine the amounts of oxidizingand reducing agents in solution. For example, a solution ofhydrogen peroxide, H2O2, can be titrated against a solution ofpotassium permanganate, KMnO4. The following equation representsthe reaction:
2KMnO4(aq)+H2O2(aq)+3H2SO4(aq)?O2(g)+2MnSO4(aq)+K2SO4(aq)+4H2O(l)
A certain amount of hydrogen peroxide was dissolved in 100. mLof water and then titrated with 1.68 M KMnO4. What mass of H2O2 wasdissolved if the titration required 20.3mL of the KMnO4solution?
