Popis: | An experiment is presented which allows students to balance an oxidation-reduction reaction equation and use the reaction to analyze a consumer product. The experiment calls for students to balance the reaction of H2O2 and MnO4- two different ways (one assuming that H2O2 is the oxygen source and a second assuming that MnO4- is the oxygen source). They then determine which of these balanced equations has the correct stoichiometry by titrating a standard H2O2 solution with KMnO4. Finally, they use the correct balanced equation to determine the mass percent of H2O2 in a commercially available, "environmentally friendly" oxygen bleach solution. |
