Why is beryllium fluoride soluble in water?
Fluorides of alkaline earth metals except BeF2 are insoluble in water. The solubility of BeF2 in water is due to the higher hydration energy on account of the smaller size of Be2+ ion and F− ion and the high charge density of Be2+ ion. Q3. If the lattice enthalpy has a larger value, the compound is less soluble.
What is beryllium fluoride used for?
Application: Beryllium fluoride is a chemical used in protein crystallography as a mimic of phosphate. ADP and beryllium fluoride together tend to bind to ATP sites and inhibit protein action, making it possible to crystallise proteins in the bound state. Principal precursor for the manufacture of beryllium metal.

How is beryllium fluoride harmful to the environment?
The physical and chemical properties: a chemical substance, white powder or crystal, solubility: soluble in water, soluble in ethanol, insoluble in nitrate, the relative density (water = 1) : 1.9860. It is harmful to the environment and can cause pollution to the water body.
What happens if you inhale too much beryllium?
In contrast, the toxicity of inhaled beryllium is well-documented. Humans inhaling “massive” doses of beryllium compounds (such as the water soluble sulfate, fluoride, chloride, and oxide) may develop acute berylliosis (Constantinidis, 1978).
What is the LD50 of beryllium in fluoride?
The increased toxicity of beryllium in the presence of fluoride has been noted as early as 1949. The LD50 in mice is about 100 mg/kg by ingestion and 1.8 mg/kg by intravenous injection.
What is the formula for beryllium fluoride in water?
Beryllium fluoride is the inorganic compound with the formula BeF2. This white solid is the principal precursor for the manufacture of beryllium metal. Its structure resembles that of quartz, but BeF 2 is highly soluble in water.
