Beryllium bromide is the chemical compound with the formula BeBr2. It is very hygroscopic and dissolves well in water.

[edit] Reactions

Beryllium bromide can be prepared by reacting beryllium metal with elemental bromine at temperatures of 500°C to 700°C[1]:

Be + Br2 → BeBr2

Beryllium bromide is also formed when beryllium oxide with hydrobromic acid (in aqueous solution) or hydrogen bromide (in the gas phase) [2]:

BeO + 2 HBr → BeBr2 + H2O
