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:

Question

2KMnO4(aq)+H2O2(aq)+3H2SO4(aq)-»O2(g)+2MnSO4(aq)+K2SO4(aq)+4H2O(l)

A certain amount of hydrogen peroxide was dissolved in 100. \rm mL of water and then titrated with 1.68 M \rm KMnO_4. How much \rm H_2O_2 was dissolved if the titration required 12.8 mL of the \rm KMnO_4 solution?

Answer 1
