Oscillating Reaction: Briggs-Rauscher
Demonstration Notes, Warnings, Safety Information
corrosive, chemical irritants
H2O2 and NaIO3 are strong oxidizing agents. H2SO4 is a strong acid. Avoid skin contact with these substances, and wash away any spills with large amounts of water. Oscillating reactions are difficult to get to work correctly. Care must be taken in the preparation and mixing of the reagents.
These demonstration videos are not meant as tools to teach chemical demonstration techniques. They are meant as a tools for classroom use. Many of the demonstrations present safety hazards or are difficult for an entire class to observe as live demos. If you wish to perform the demonstrations shown here, you should obtain a copy of Shakhashiri's Chemical Demonstrations Vol. 1-4 (1), Gilbert, Alyea, Dutton and Dreisbach's Tested Demonstrations in Chemistry, Vol. I and II (2) and Ellis, Geselbracht, Johnson, Lisensky, and Robinson's Teaching General Chemistry: A Materials Science Companion (3).
