Ii is very light and its density is half that of iron. Barium oxidizes in air, reacts vigorously with water to form the hydroxide, liberating hydrogen. Barium reacts with almost all the non-metals, forming often poisoning compounds.
Barium acetate is the salt of barium(II) and acetic acid
Barium chloride is the inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium.
