Preparation of
bismuth nitrate
(1) Dissolve bismuth oxide with nitric acid, the chemical equation is as follows:
6HNO3+Bi2O3=2Bi(NO3)3+3H2O
(2) Bismuth nitrate can also be obtained by reacting bismuth and dilute nitric acid, and evaporating and crystallizing. The chemical equation is as follows:
Bi+4HNO3=Bi(NO3)3+NO↑+2H2O
(3) When concentrated nitric acid is used in the reaction, bismuth(III) oxide may be produced. The chemical equation is as follows:
2Bi+2HNO3=Bi2O3+2NO↑+H2O
