In weakly acidic to basic conditions, inorganic bismuth salts are hydrolyzed to the corresponding oxide products, commonly referred to as “basic,” “oxy”, or “sub-” salts, with formation of the bismuthyl ion (BiO+), which has a low aqueous solubility. In the case of bismuth oxychloride (BiOCl), solubility increases with acidity possibly due to the liberation of
Bi3+ from BiO+ by the hydronium ion,643 but the formation of anionic [BiCl4]- is also postulated on the basis that BiOCl is more soluble in hydrochloric acid than in nitric acid.644 Moreover, the solubility of BiCl3 in nitric acid increases with addition of NaCl.
