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]

Contents

Synthesis

Actinium nitrate can be obtained by dissolving actinium or actinium hydroxide in nitric acid.

Ac(OH)3 + 3HNO3 → Ac(NO3)3 + 3H2O

Properties

Actinium(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]
