Iron(III) fluoride, also known as ferric fluoride, are inorganic compounds with the formula FeF 3 (H 2 O) x where x = 0 or 3. They are mainly of interest by researchers, unlike the related iron(III) chloride. Anhydrous iron(III) fluoride is white, whereas the hydrated forms are light pink. [2]
The fluorine–fluorine bond of the difluorine molecule is relatively weak when compared to the bonds of heavier dihalogen molecules. The bond energy is significantly weaker than those of Cl 2 or Br 2 molecules and similar to the easily cleaved oxygen–oxygen bonds of peroxides or nitrogen–nitrogen bonds of hydrazines. [8]
Iron(II) fluoride or ferrous fluoride is an inorganic compound with the molecular formula FeF 2. It forms a tetrahydrate FeF 2 ·4H 2 O that is often referred to by the same names. The anhydrous and hydrated forms are white crystalline solids.
Iron reacts with fluorine, chlorine, and bromine to form iron(III) halides. These reactions are in the form of: 2Fe + 3X 2 → 2FeX 3 [15] However, when iron reacts with iodine, it forms only iron(II) iodide. Fe + I 2 → FeI 2. Iron wool can react rapidly with fluorine to form the white compound iron(III) fluoride even in cold
As with other iron alloys, around 3 kg (6.6 lb) metspar is added to each metric ton of steel; the fluoride ions lower its melting point and viscosity. [ 65 ] [ 190 ] Alongside its role as an additive in materials like enamels and welding rod coats, most acidspar is reacted with sulfuric acid to form hydrofluoric acid, which is used in steel ...

Fluoride was measured at 8 milligrams per liter in the groundwater of some villages in China, while some Canadian waters contain levels of less than 0.05 milligrams per liter, according to a World ...
Organofluorine compounds are pervasive. Many drugs, many polymers, refrigerants, and many inorganic compounds are made from fluoride-containing reagents. Often fluorides are converted to hydrogen fluoride, which is a major reagent and precursor to reagents. Hydrofluoric acid and its anhydrous form, hydrogen fluoride, are particularly important. [4]
