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
