Bismuth(III) sulfide is isostructural with stibnite (stibnite is one of the forms of antimony(III) sulfide). Bismuth atoms are in two different environments, both of which have 7 coordinate Bismuth atoms, 4 in a near planar rectangle and three more distant making an irregular 7-coordination group. It can react with acids … See more Bismuth(III) sulfide (Bi2S3) is a chemical compound of bismuth and sulfur. It occurs in nature as the mineral bismuthinite. See more Bismuth(III) sulfide can be prepared by reacting a bismuth(III) salt with hydrogen sulfide: 2 Bi + 3 H2S → Bi2S3 + 6 H Bismuth (III) sulfide can also be prepared by the reaction of elemental bismuth and elemental sulfur in … See more It is used as a starting material to produce many other bismuth compounds. See more WebJan 1, 2024 · This method of producing bismuth sulfide simply involves the precipitation of the compound in a controlled manner from a homogeneous solution. It is achieved by using the precursors of bismuth and sulfur ions with appropriate stability constant. The reaction between the two ions is as shown in equation 1. 2Bi3+ (aq) + 3S2− (aq) → Bi2S3 (s) (1)
