Incomplete Combustion of Hydrogen: Trapping a Reaction Intermediate
Mattson, Bruce; Hoette, Trisha
Journal of Chemical Education, v84 n10 p1668-1670 Oct 2007
The combustion of hydrogen in air is quite complex with at least 28 mechanistic steps and twelve reaction species. Most of the species involved are radicals (having unpaired electrons) in nature. Among the various species generated, a few are stable, including hydrogen peroxide. In a normal hydrogen flame, the hydrogen peroxide goes on to further oxidation resulting in water. In this classroom demonstration, a hydrogen flame is played across the face of an ice cube and the combustion is quenched in an incomplete state. The solution that results contains aqueous hydrogen peroxide that can be tested with two simple chemical tests. (Contains 1 figure and 2 notes.) [This article was checked by Michelle S. Applebee.]
