Iron (II) sulfide, also popular as iron sulfide or ferrous sulfide, is an inorganic, water-insoluble compound represented by the chemical formula FeS [1, 2]. In IUPAC nomenclature, it is called sulfanylideneiron [1]. It naturally occurs as the minerals troilite and pyrrhotite [3].
26 de abr. de 2024 · Iron (II) sulfide, or FeS, is made by directly combining iron and sulfur. To do this safely in a lab, mix 7 grams of iron powder with 4 grams of sulfur in a porcelain crucible. This mixture is based on the chemical reaction ensuring the right balance between the iron and sulfur. Fe + S → FeS.

With hydrochloric acid it decays according to the following reaction equation: Fe 2 S 3 + 4 HCl → 2 FeCl 2 + 2 H 2 S + S Greigite. Greigite, with the chemical formula Fe 2+ Fe 3+ 2 S 4, is a mixed valence compound containing both Fe(III) and Fe(II). It is the sulfur equivalent of the iron oxide magnetite (Fe 3 O 4).
