Barium chloride is an inorganic compound with the formula BaCl₂. It is one of the most common water-soluble salts of barium. Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame. It is also hygroscopic, converting to the dihydrate BaCl₂·2H₂O, which are colourless crystals with a bitter salty taste. It has limited use in the laboratory and industry.^[7]^[3]
