I need to: DETERMINE THE CONCENTRATION OF HYDROGEN PEROXIDE IN THE SOLUTION how ?? THEORY Titrimetry, or titrimetric analysis, is an example of a so-called classical method of analysis. Titrimetry is a convenient method of getting very small amounts of chemicals in to a reaction because the method involves the use of dilute solutions of reactants. Hydrogen peroxide reacts with potassium iodide according to the reaction given below: HB2BOB2B + 2HP+P + 2IP-P = IB2B + 2HB2BO (equation...

hydrogen peroxide titration, concentration of KMnO4 is 0.025 and
the concentration of H2O2 from the mol ratio is 0.882 M
o Estimated Concentration of Diluted Peroxide: . Remember when we had a 1:1 ratio we wanted the concentrations of NaOH and HCl to be similar. So if NaOH was 0.025 M then we would want HCl to be 0.025 M. In this case, we have a 5:2 ratio so if the concentration of KMnO4 is approximately 0.025M then we need...

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...
