Specification
Barium chloride dihydrate, with CAS number of 10326-27-, can be called Barium chloride hydrate (1:2:2); Dichlorobarium dihydrate. Barium chloride dihydrate is a white crystalline powder. It contains two molecules of water. It is one of the most important water soluble salts of Barium. Like other barium salts, it is toxic and imparts a yellow-green coloration to a flame. It is also hygroscopic.
