Barium Chloride

Introduction of Barium Chloride

Barium Chloride with chemical formula BaCl2 is a white ionic chemical compound and is one of the most important barium salts that is water-soluble and has a solubility of about 380 grams per liter (g/l) at 200ºC in water. Barium chloride can be crystallized in two structures of “fluorite” cubic and “orthorhombic zinc chloride”. It is soluble in methanol but insoluble in ethanol.
