  • Antimony trisulfide - Wikipedia

    OverviewPreparation and reactionsStructure

    Sb2S3 can be prepared from the elements at temperature 500-900 °C: 2Sb + 3S → Sb2S3Sb2S3 is precipitated when H2S is passed through an acidified solution of Sb(III). This reaction has been used as a gravimetric method for determining antimony, bubbling H2S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb2S3 which turns black under the reaction conditions.
