Abstract
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.

Chemistry Teacher Connection

The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.


C&EN CLICs

Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students. 


JCE Collections Available
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
