Oxoacids and their salts Hypofluorous acid, HOF
Fluorine is unique among the halogens in forming no species in which it has a formal oxidation state other than _1. The only known oxoacid is hypofluorous acid, HOF, which is unstable and does not ionize in water but reacts according to equation 1.1; no salts are known. It is obtained by passing F2 over ice at 230K (equation 1.2) and condensing the gas produced. At 298 K, HOF decomposes rapidly (equation 1.3).
