Bismuth compounds hydrogen halides

Ionic compounds are usually scarcely soluble, but covalent compounds such as hydrogen halides and many organic compounds are soluble. Examples are hydrocarbons, carboxylic acids, acid chlorides, nitriles, aldehydes, ketones, alcohols, amines and nitrocompounds, but the conductivities of their solutions are very small. Many acceptor halides such as those of aluminium, titanium(IV), tin(IV), phosphorus(V), arsenic(III) and bismuth(III) as well as ferric chloride show reasonable solubilities due to interaction with liquid hydrogen sulphide. Solvates of AICI3, AlBrs, TiCl4, SnCU, BCI3 and others have been described .
