Description :
Lithium bromide, or LiBr, is a chemical compound of lithium and bromine. Its extreme hygroscopic character makes LiBr useful as a desiccant in certain air conditioning systems.
LiBr is prepared by treatment of lithium carbonate with hydrobromic acid. The salt forms several crystalline hydrates, unlike the other alkali metal bromides. The anhydrous salt forms cubic crystals similar to common salt.
Lithium Hydroxide and Hydrobromic Acid (Aqueous solution of Hydrogen Bromide) will precipitate Lithium Bromide in the presence of water.
LiOH + HBr → LiBr + H2O
