Actinium(III) nitrate is an inorganic compound, actinium salt of nitric acid with the chemical formula Ac(NO3)3. The compound looks like white substance, readily soluble in water.[1]
Synthesis
Actinium nitrate can be obtained by dissolving actinium or actinium hydroxide in nitric acid.
- [math]\displaystyle{ \mathsf{Ac(OH)_3 + 3HNO_3 \ \xrightarrow{}\ Ac(NO_3)_3 + 3H_2O} }[/math]
Properties
Actinium(III) nitrate decomposes on heating above 600 °C:
- [math]\displaystyle{ \mathsf{4Ac(NO_3)_3=2Ac_2O_3+12NO_2+3O_2} }[/math]
This salt is used as a source of Ac3+ ions to obtain insoluble actinium compounds by precipitation from aqueous solutions.[2]
