Synthesis
editActinium nitrate can be obtained by dissolving actinium or actinium hydroxide in nitric acid.
- Ac(OH)3 + 3HNO3 → Ac(NO3)3 + 3H2O
Properties
editActinium(III) nitrate decomposes on heating above 600 °C:
- 4Ac(NO3)3 → 2Ac2O3 + 12NO2 + 3O2
This salt is used as a source of Ac3+ ions to obtain insoluble actinium compounds by precipitation from aqueous solutions.[2]
