Beryllium nitrate, also known as beryllium dinitrate, is an ionic beryllium salt of nitric acid with the chemical formula Be(NO3)2.[2] Each formula unit is composed of one Be2+ cation and two NO3− anions.
Hazards
Beryllium nitrate is a toxic chemical,[2] like all other beryllium compounds. It is also an irritant in small doses. When burned, it gives off irritating or toxic fumes. However, when massive short-term exposure occurs, acute pneumonitis can set in, but symptoms do not manifest themselves for 3 days.[2]
Preparation
Beryllium nitrate can be prepared by reacting beryllium hydroxide in nitric acid.[3]
- Be(OH)2 + 2 HNO3 → Be(NO3)2 + 2 H2O
