Question

laboratory prepared method of iron III sulphide
​

Answer 1

Explanation:

Preparation and properties Fe2S3 is prepared by addition of refrigerated iron(III) chloride solution to also cooled sodium sulfide solution. It is also produced as a side-product of desulfurization of fuel gasses. The gas is pumped through a container of hydrated iron(III) oxide, which combines with hydrogen sulfide.

Solubility in water: very slightly soluble

Chemical formula: Fe2S3

Molar mass: 207.90 g/mol

Melting point: decomposition

Answer 2

Answer:

Fe2S3 is prepared by addition of refrigerated iron(III) chloride solution to also cooled sodium sulfide solution.[citation needed]

2 FeCl3 + 3 Na2S → Fe2S3↓ + 6 NaCl

It is also produced as a side-product of desulfurization of fuel gasses. The gas is pumped through a container of hydrated iron(III) oxide, which combines with hydrogen sulfide.

Fe

2O

3(s) + H

2O(l) + 3 H

2S(g) → Fe

2S

3(s) + 6 H

2O(l)

Reactions Edit

Iron(III) sulfide decays at a temperature over 20 °C into iron(II) sulfide (FeS) and elemental sulfur:[2]

Fe2S3 → 2 FeS + S↓

With hydrochloric acid it decays according to the following reaction equation:[3]

Fe2S3 + 4 HCl → 2 FeCl2 + 2 H2S↑ + S↓
