Iron (III) sulfide is not soluble in water.
The solubility in water is extremely low.
Insoluble
Ionic
Iron (|) Sulfide
Ionic compound
If you are talking the element sulfur, it is not soluble in water so you can just filter it off. A coffee filter would work. If you are talking the sulfide ion, S-2, you treat it withferric chloride to form the solid Fe2S3, which can then be filtered.
The chemical formula for ironite trisulfide is Fe2S3. It consists of two iron (Fe) atoms and three sulfur (S) atoms.

The oxidation number of Fe in Fe2S3 is +3. This is because the overall charge of the Fe2S3 compound is 0, and since there are 2 Fe atoms each with an unknown oxidation number "x" and 3 S atoms each with an oxidation number of -2, the sum of the oxidation numbers must equal 0. Solving for x gives +3 for the oxidation number of Fe.
Fesub2 S
decomposition
ferric indicates the iron is +3 as opposed to +2 for ferrous sulfide indicates that there is sulfur with a -2 charge the formula is Fe2S3 two iron ions with a +3 = +6 3 sulfur ions with a -2 = -6 -6+6 = 0
+3 for Fe -2 for S
