What is Silver(II) fluoride?
'''Silver(II) fluoride''', also known as '''argentic fluoride''', is a [[chemical compound]]. Its chemical formula is AgF<sub>2</sub>. It has [[silver]] in its +2 [[oxidation state]]. It also contains [[fluoride]] [[ion]]s. ==Properties== It is a white or gray [[crystalline]] solid. It is usually black or brown because of [[wikt:impurity|impurities]]. It is a powerful [[oxidizing agent]]. It is one of the only silver compounds that is in the +2 oxidation state. Most of the silver compounds are in the +1 oxidation state. It can react with glass. It should be stored in certain fluorinated plastics. It is extremely reactive. It reacts with [[xenon]]. It also reacts with water to make [[oxygen]] and [[hydrofluoric acid]]. It reacts with [[acid]]s to make [[ozone]]. It reacts with [[iodide]] to make [[iodide]]. It also reacts with hydrogen peroxide to make oxygen. It is very expensive. Only a little is made each year. ==Preparation== Silver(II) fluoride is made by reacting [[fluorine]] with [[silver(I) oxide]]. It can also be made by reacting [[silver(I) fluoride]] or [[silver chloride]] with fluorine. ==Uses== Silver(II) fluoride is used to add fluoride to certain chemical compounds. It is not used much because it is very expensive. ==Safety== Silver(II) fluoride is very corrosive and toxic. It reacts with water to make toxic hydrofluoric acid. It also corrodes glass. ==Related pages== *[[Potassium fluoride]] [[Category:Fluorine compounds]] [[Category:Silver compounds]] {{Fluorine compounds}}
