What is Tin(IV) fluoride?
'''Tin(IV) fluoride''', also known as '''stannic fluoride''', is a [[chemical compound]]. Its chemical formula is SnF<sub>4</sub>. It contains [[tin]] and [[fluoride]] [[ion]]s. The tin is in its +4 [[oxidation state]]. ==Properties== Tin(IV) fluoride is a colorless solid. Its [[melting point]] is very high. It reacts with [[alkali metal]] fluorides like [[potassium fluoride]] to make hexafluorostannates, compounds that have the SnF<sub>6</sub><sup>2-</sup> ion in them. ==Preparation== Tin(IV) fluoride is made by reacting tin and [[fluorine]]. It can also be made by reacting [[hydrogen fluoride]] with [[tin(IV) chloride]]. ==Uses== It is sometimes used in [[toothpaste]], although [[tin(II) fluoride]] is more common. ==Related pages== *[[Tin(IV) bromide]] *[[Tin(IV) iodide]] *[[Tin(IV) oxide]] {{chem-stub}} [[Category:Tin compounds]] [[Category:Fluorine compounds]] {{Fluorine compounds}}
