Bismuth(III) nitrate is a salt composed of bismuth in its cationic +3 oxidation state and nitrate anions. The most common solid form is the pentahydrate.^[3] It is used in the synthesis of other bismuth compounds.^[4] It is available commercially. It is the only nitrate salt formed by a group 15 element, indicative of bismuth's metallic nature.^[5]

Preparation and reactions[edit]

Bismuth nitrate can be prepared by the reaction of bismuth metal and concentrated nitric acid.^[6]

Bi + 4HNO₃ → Bi(NO₃)₃ + 2H₂O + NO

It dissolves in nitric acid but is readily hydrolysed to form a range of oxynitrates when the pH increases above 0.^[7]

It is also soluble in acetone, acetic acid and glycerol but practically insoluble in ethanol and ethyl acetate.^[8]

Some uses in organic synthesis have been reported for example the nitration of aromatic compounds and selective oxidation of sulfides to sulfoxides.^[8]

Bismuth nitrate forms insoluble complexes with pyrogallol and cupferron and these have been the basis of gravimetric methods of determining bismuth content.^[9]

On heating bismuth nitrate can decompose forming nitrogen dioxide, NO₂.^[10]

Structure[edit]

The crystal form is triclinic, and contains 10 coordinate Bi³⁺, (three bidentate nitrate ions and four water molecules).^[1]
