Iron (III) sulfide Fe 2 S 3 is a solid, black substance which, however, breaks down into a yellowish-gray powder mixture of iron (II) sulfide and sulfur at room temperature .
Appearance and properties
If a likewise cooled aqueous solution of sodium sulfide is added to an ice-cooled aqueous solution of iron (III) chloride , a black precipitate of iron (III) sulfide is formed
which, however, breaks down into FeS and sulfur above 20 ° C
With hydrochloric acid , decomposition takes place according to the following reaction equation:
The compound has a crystal structure of spinel .
