Part B 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: 2KMnO4 (aq) + H₂O2 (aq) + 3H2SO4 (aq) → 302(g) + 2MnSO4 (aq) + K₂SO4 (aq) + 4H₂O(1) A certain amount of hydrogen peroxide was dissolved in 100. mL of water and then titrated with 1.68 M KMnO4. What mass of H₂O2 was dissolved if the titration required 14.3 mL of the KMnO4 solution?
