Description

White Hygroscopic crystals. Lithium chloride is one of the most hygroscopic salts known. In a closed environment, a saturated solution of lithium chloride will form an equilibrium at a relative humidity of about 12.4% (20C). Lithium chloride salts are also used in pyrotechnics to produce red colors, as a Desiccant, as a soldering Flux, and as a carbon dioxide stabilizer in carbonate drinks.
