Iron(II) chloride (FeCl₂) is an inorganic salt compound consisting of iron in the +2 oxidation state bonded to chloride ions, typically available as a hydrated crystalline solid. While not a structural metal itself, FeCl₂ serves as a precursor material and chemical reagent in industrial processes, notably in water treatment, metal surface preparation, and synthesis of iron-containing compounds. Engineers select FeCl₂ for applications requiring controlled iron chemistry, corrosion inhibition through ferrous ion chemistry, or as a starting material for specialized coatings and catalysts, rather than for load-bearing structural purposes.
