Description and Uses
Barium dichloride is a white solid, odorless, hygroscopic chemical substance. Barium dichloride is used in the manufacture of pigments, in the manufacture of other barium salts and in fireworks to give a bright green color. It is one of the most common watersoluble salts of barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. Barium chloride has wide application in the laboratory.
Barium chloride (BaCl2) is used in the manufacture of paint pigments and dyeing textiles and as an additive in oils. It is also used as a water softener.
