VerwendenFerrous 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.
synthetischeIron(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.
