Actinium(III) hydroxide is a white radioactive solid with the chemical formula of Ac(OH)3.
Preparation
[edit]Actinium(III) hydroxide may be formed from soluble actinium salts and alkalis or ammonia water, and the resulting gel is precipitated as the product:[1]
- Ac3+ + 3 OH− → Ac(OH)3↓
Its solubility is slightly greater than that of lanthanum hydroxide, but it is still insoluble in water.
Chemical properties
[edit]Actinium(III) hydroxide is an alkaline hydroxide, it can react with acids to obtain actinium salts:[1]
- Ac(OH)3 + 3 HNO3 → Ac(NO3)3 + 3 H2O
