Chemical Properties    Blackish brown powder
Physical properties    Brownish black orthogonal crystal; density 6.78 g/cm3; hardness 2 Mohs; melts at 850°C; insoluble in water; soluble in acids.
Occurrence    Bismuth sulfide occurs in nature as the mineral bismuthinite (bismuth glance). It is used as a starting material to produce many other bismuth compounds.
Preparation    The compound occurs in nature as mineral bismuthinite. It can be prepared in the laboratory by passing hydrogen sulfide into a solution of bismuth chloride or any soluble bismuth salt:
2BiCl3 + 3H2S → Bi2S3 + 6HCl
Alternatively, bismuth sulfide may be obtained by melting a mixture of bismuth and sulfur.
2Bi + 3S → Bi2S3
