Bismuth trichloride is a chemical bond between bismuth and chlorine with the formula BiCl3. It is a colorless solid.

Production and representation

Bismuth ( III ) chloride can be extracted with hydrochloric acid either directly from the elements or by reaction of bismuth ( III ) oxide.

Properties

Bismuth ( III ) chloride forms white, deliquescent crystals that smell of hydrogen chloride. The structure of the bismuth ( III ) chloride equivalent to that of the bismuth ( III) fluoride. It represents a distorted since uranium ( III) chloride structure.

Bismuth ( III) chloride reacts with water to form insoluble Bismutchloridoxid, the reaction can however be suppressed by acidification.

Bismuth ( III ) chloride is a Lewis acid chloride with donors such as sodium chloride to form anionic complexes of the form ECl4, ECl52 - or - ECl63.

In contrast to arsenic and antimony ( III) chloride are bismuth ( III) chloride will not allow bismuth ( V) - chloride oxidized.
