Preparation methods
PreparationIron(II) hydroxide may be prepared by precipitation of an iron(II) salt solution with caustic soda or caustic potash in the absence of air. Pure compound may be obtained by mixing solutions of caustic potash and iron(II) sulfate— both the solutions made in freshly boiled water—in a reducing atmosphere of hydrogen: Fe2+ + 2OHˉ → Fe(OH)2.
