Chemical Properties of Sulfur Dioxide
Demonstration Notes, Warnings, Safety Information
toxic gas, irritant gas, toxic chemicals
Sulfur dioxide is toxic and a strong irritant with a powerful choking odor. The chemicals used in these reactions are toxic. Exposure of the skin to these chemicals should be avoided.
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).
