Product Details

H. J. H. Fenton, an English chemist, discovered in 1894 that some metal ions, particularly the iron(II) ion, catalyze the decomposition of hydrogen peroxide to generate highly reactive intermediates. Fenton’s reaction has been “rediscovered” and is now used to break down a large variety of water and soil pollution molecules, e.g. phenols, pesticides, and rubber chemicals. Show students the oxidizing power of this “old-time” chemical concoction by breaking down a series of colorful and fluorescent organic molecules. Includes valuable Teacher Notes with helpful teaching tips, reproducible student worksheets, and enough materials to perform the demonstration seven times. Concepts: Catalyst, green chemistry, emission spectra, redox reactions. Time Required: 20 minutes Materials Provided: Hydrogen peroxide, ferrous ammonium sulfate, sulfuric acid solution, green food dye solution, tonic water (quinine), fluorescein solution, test tubes.

Performance Expectations

HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
