Lithium chloride

CAS number : 7447-41-8

Molecular weight :42.39

Molecular formula/chemical symbol :LiCl

Description :
 

Lithium chloride is a chemical compound with the formula LiCl. The salt is a typical ionic compound, although the small size of the Li⁺ ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83g/100 mL of water at 20 °C) and its hygroscopic properties.

The salt forms crystalline hydrates, unlike the other alkali metal chlorides. Mono-, tri-, and pentahydrates are known. It also absorbs up to four equivalents of ammonia. As with any other ionic chlorides, solutions of lithium chloride can serve as a source of chloride ion, e.g. forming a precipitate upon treatment with silver nitrate:

LiCl + AgNO₃ → AgCl + LiNO₃
