Bismuth(III) nitrate pentahydrate (Bi(NO3)3•5H2O)-Crystalline

Characteristic




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. It is used in the synthesis of other bismuth compounds. It is available commercially. It is the only nitrate salt formed by a group 15 element, indicative of bismuth's metallic nature.

Application




Luminous paints, preparation of bismuth saltsBismuth(III) nitrate pentahydrate is an oxidant for a variety of 4-substituted Hantzsch 1,4-dihydropyridines. It also serves as a reagent for selective oxidation of sufides to sulfoxides. Further, it is involved in the preparation of Dragendorff reagent and used as a TLC stain. It is also used to prepare other bismuth compounds.
