Iron (III ) sulphide Fe2S3 is a solid, black substance, but decomposes at room temperature into a yellowish-gray powder mixture of iron (II ) sulfide, and sulfur.

Preparation and Properties

Is added to an ice-cooled aqueous solution of iron ( III ) chloride also a cooled aqueous solution of sodium sulfide, then a black precipitate of iron ( III ) sulfide forms

However, the above 20 ° C in FeS and sulfur decomposes

With hydrochloric acid is a decomposition according to the following equation:
