Tellurium & oxygen - a photo on Flickriver

Tellurium & oxygen

            A tiny piece of Tellurium burns readily in a stream of oxygen with a bright bluish green white flame, just in side a glass tubing, to form Tellurium Dioxide (TeO2), as a white smoke. 

The oxide, TeO2, is almost insoluble in water, but does show weak acidic behaviour & will dissolve readily in caustic alkali solution to form Tellurite salts.

Tellurium compounds are rather toxic & has a property of causing particularly bad body odours, so great care should be exercised in handling tellurium & its compounds.
