Iron(iii) Sulfide Formula
Composition and also Synthesis
It is created by the enhancement of cooled iron(iii) chloride solution to refrigerated salt sulfide solution, as stood for by the adhering to equation:
2FeCl3 + 3Na2S → Fe2S3 + 6NaCl
It can also be synthesized as a by-product the desulfurization of hydrogen sulfide gas that is passed through hydrated iron(iii) oxide:
Fe2O3 + 3H2S + H2O → Fe2S3 + 4H2O
Iron(iii) Sulfide
Reaction with Hydrogen Chloride
It experience a decomposition reaction when merged with hydrochloric acid <4>:
Fe2S3 + 4HCl → 2FeCl2 + 2H2S + S
