용도Ferrous chloride (FeCl2) is used in pharmaceutical preparations, for sewage treatment, and as a mordant (which fixes dyes so that they will not run) in textiles.
일반 설명Ferrous chloride is a greenish white crystalline solid. Ferrous chloride is soluble in water. Ferrous chloride is noncombustible. Ferrous chloride is used in sewage treatment, in dyeing of fabrics, and for many other uses.
Iron(II) chloride is prepared by passing chlorine or hydrogen chloride gasover iron at red heat or 700°C: Fe + 2HCl → FeCl2 + H2 Fe + Cl2 → FeCl2 It also may be produced by the reduction of iron(III) chloride with hydrogenor other reducing agents at elevated temperatures: 2FeCl3 + H2 → 2FeCl2 + 2HCl The tetrahydrate is obtained by dissolving the metal in hydrochloric acidfollowed by crystallization at room temperature. Fe + 2HCl + 4H2O → FeCl2•4H2O + H2 The tetrahydrate gradually loses water when heated above 105°C formingdihydrate, monohydrate and the anhydrous salt. At 220°C it loses all its waterof crystallization.
