What is Tellurium(IV) fluoride?
'''Tellurium(IV) fluoride''', also known as '''tellurium tetrafluoride''', is a [[chemical compound]]. Its chemical formula is TeF<sub>4</sub>. It contains [[tellurium]] in its +4 [[oxidation state]]. It also contains [[fluoride]] [[ion]]s. == Properties == Tellurium(IV) fluoride is a white solid. It reacts with water to make [[tellurium dioxide]] and [[hydrofluoric acid]]. It reacts with many metals when heated. == Preparation == It is made by reacting [[tellurium dioxide]] with [[sulfur tetrafluoride]]. It can also be made by reacting cold [[fluorine]] with tellurium. Another way is reacting [[selenium tetrafluoride]] with warm tellurium dioxide. Fluorine can also react with [[tellurium(II) chloride]] or [[tellurium(II) bromide]] to make tellurium(IV) fluoride. == Related pages == *[[Tellurium(VI) fluoride]] *[[Tellurium(IV) chloride]] [[Category:Tellurium compounds]] [[Category:Fluorine compounds]] {{Fluorine compounds}}
