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)?3O2(g)+2MnSO4(aq)+K2SO4(aq)+4H2O(l)

A titration is a procedure for determining the concentration of a solution by allowing it to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation-reduction reactions are used in titrations. For example, to find the concentration of an HCI solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCl from a calibrated tube called a buret. An indicator is also present and it will change color...
The concentration of hydrogen peroxide solution can be determined by titration against a standardized solution or potassium permanganate in acidic medium according to the following equation: 2MnO4 + 5H2O2 + 6H* -----> 502 + 2Mn+2 + 8H2O What is being oxidized? What is being reduced? What is the oxidizing agent? What is the reducing agent?
