Iron(iii) Sulfide Formula
Composition and Synthesis
It is produced by the addition of cooled iron(iii) chloride equipment to refrigerated sodium sulfide solution, as represented by the complying with equation:
2FeCl3 + 3Na2S → Fe2S3 + 6NaCl
It can additionally be synthesized together a by-product that desulfurization of hydrogen sulfide gas that is passed with hydrated iron(iii) oxide:
Fe2O3 + 3H2S + H2O → Fe2S3 + 4H2O
