Abstract
It is well known that the ion Bi3+ easily reacts with water (is hydrolysed) so that hydrogen ions are set free. Very little is known, however, of the nature of the reaction products. In 1936 Holmqvist2, and Prytz and Nagel4 working independently, concluded that there are certainly not only mononuclear complexes (BiOH2+, BiO+) but also polynuclear complexes containing more than one bismuth atom. Holmqvist even tried to apply the law of mass action assuming definite formulæ, namely, Bi2(OH)2+4 and Bi2(OH)+5.
