Lithium chloride
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.
