Structure and properties of Barium chloride

Post  gill on Tue Dec 21, 2010 9:25 pm


Barium chloride is the ionic chemical compound with the formula BaCl2. 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.
Barium chloride crystallizes in both the fluorite and lead chloride motifs, both of which accommodate the preference of the large Ba2+ ion for coordination numbers greater than six. In aqueous solution BaCl2 behaves as a simple salt; in water it is a 1:2 electrolyte and the solution exhibits a neutral pH. Barium chloride reacts with sulfate ion to produce a thick white precipitate of barium sulfate.
