Percentage of H₂O₂ in Your Drugstore Hydrogen Peroxide

This lab is an introduction to Redox titration. Students use a redox probe and titration to determine the hydrogen peroxide content of a drugstore formulation.

Students will be expected to apply knowledge of balancing reduction-oxidation reactions and half reactions in order to complete this lab. They standardize a solution of potassium permanganate using ferrous ammonium sulfate, then use the permanganate to titrate against a diluted sample of drugstore 3% hydrogen peroxide.
