Question

Bismuth chloride and excess water reaction

Answer 1

Bismuth Trichloride, BiCl3, appears to have been prepared first by Boyle in 1664, and later by Poli in 1713, by heating a mixture of bismuth and mercuric chloride. It may also be obtained by the direct union of the elements; by the action of hydrochloric acid upon bismuth in the presence of air, concentrated hydrochloric acid upon bismuth trioxide, pentoxide or trisulphide, or aqua regia upon bismuth; by heating bismuth trioxide, pentoxide or trisulphide in a current of chlorine, the oxides in a current of hydrogen chloride, or bismuth with phosphorus trichloride; or by the action of silicon tetrachloride or sulphur monochloride on bismuth trioxide.
