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: 2 kmno4 (aq) + h2o2 (aq) + 3 h2so4 (aq) → 3 o2 (g) + 2 mnso4 (aq) + k2so4 (aq) + 4 h2o (l) a certain amount of hydrogen peroxide was dissolved in 100. ml of water and then titrated with 1.66 m kmno4. what mass of h2o2 was dissolved if the titration required 13.2 ml of the kmno4 solution?
