What is Antimony pentafluoride?
[[File:Antimony(V)fluroide liquid phase.svg|thumb|200px|Antimony(V) fluoride liquid phase.]] '''Antimony pentafluoride''', also known as '''antimony(V) fluoride''', is a [[chemical compound]]. Its chemical formula is SbF<sub>5</sub>. It has five [[antimony]]-[[fluorine]] [[chemical bond|bond]]s. The antimony is in its +5 [[oxidation state]]. ==Properties== Antimony pentafluoride is a colorless viscous liquid. It is an extremely powerful [[oxidizing agent]] and very reactive. [[Sodium]], [[Potassium]] and [[Phosphorus]] (red or [[White phosphorus|yellow]]) can burn on contact with it. It can [[oxidation|oxidize]] [[oxygen]] in the present of [[fluorine]], which makes SbF<sub>5</sub>/F<sub>2</sub> mixtures one of the strongest oxidizers . It is not normal as oxygen normally oxidizes other things; it does not get oxidized commonly. It can make very strong [[acid]]s ([[fluoroantimonic acid]]) when mixed with [[hydrogen fluoride]]. It was used in the first reaction that used fluorides to make fluorine. ==Preparation== It is made by reacting [[antimony pentoxide]] or [[antimony pentachloride]] with hydrofluoric acid. It can also be made by reacting [[antimony trifluoride]] with fluorine. ==Uses== It is used to make very strong acids. [[Fluoroantimonic acid]] is the notable superacid formed by mixing SbF<sub>5</sub> and [[Hydrogen fluoride|HF]]. It was also used in the first reaction that formed [[Fluorine]] gas. ==Safety== Antimony pentafluoride reacts with most chemical compounds. It is extremely corrosive and poisonous. It is a powerful oxidizer. It violently forms Hydrogen Fluoride in contact with water and biological tissues. ==Related pages== *[[Antimony tribromide]] *[[Bismuth pentafluoride]] *[[Antimony tetroxide]] [[Category:Antimony compounds]] [[Category:Fluorine compounds]] {{Fluorine compounds}}
