Beryllium chloride, also known as beryllium dichloride in IUPAC nomenclature, is an inorganic compound of beryllium and chloride represented by the chemical formula BeCl2 . It can attract and hold water from the surrounding environment (hygroscopic compound) and dissolves well in several polar solvents .
How is Beryllium Chloride Prepared
It is synthesized by the reaction of beryllium with chlorine at a temperature of about 250 °C, which is represented by the following equation :
Be + Cl2 → BeCl2
BeO + Cl2 + C → BeCl2 + CO
BeCl2 can also be produced by the reaction of beryllium with a diluted solution of hydrogen chloride:
Be + 2HCl → BeCl2 + H2
Reactions with Other Compounds
Beryllium Chloride with Silver Nitrate
Beryllium chloride reacts with silver nitrate dissolved in water, to form silver chloride powder and an aqueous solution of beryllium nitrate:
BeCl2 + 2AgNO3 → Be(NO3)2 + 2AgCl
