Silver(II) fluoride is a chemical compound with the formula AgF 2. It is a rare example of a silver(II) compound - silver usually exists in its +1 oxidation state . It is used as a fluorinating agent.
Silver(II,III) fluorides (disilver pentafluoride, trisilver octafluoride) [2] Ag 2 F 5, Ag 3 F 8 Silver(III) fluoride (silver trifluoride), AgF 3 Silver diammine fluoride , a material used to stop dental caries (cavities).
Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...
Although most silver halides involve silver atoms with oxidation states of +1 (Ag +), silver halides in which the silver atoms have oxidation states of +2 (Ag 2+) are known, of which silver(II) fluoride is the only known stable one. Silver halides are light-sensitive chemicals, and are commonly used in photographic film and paper.
Multiple studies have shown silver(I) fluoride to be an effective anti-caries agent, although the mechanism is the subject of current research. [27] Treatment is typically by the "atraumatic" method, in which 40% by mass aqueous silver(I) fluoride solution is applied to carious leisons, followed by sealing of the dentine with glass ionomer ...
The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III), KAgF 4).

Some metal fluorides are particularly more useful than others, including silver(I) fluoride, mercurous fluoride, cobalt(II) fluoride and aforementioned antimony. Heating the mixture of the metal fluoride and the haloalkane (chlorine and bromine are replaced readily) yields the desired fluoroalkane.
