Barium Chlorochromate, Ba(CrO3Cl)2.4CH3COOH.2H2O
Barium Chlorochromate, Ba(CrO3Cl)2.4CH3COOH.2H2O, has been obtained by the action of chromyl chloride on barium chromate in the presence of acetic acid. It is an unstable compound crystallising in yellow plates. In dry air it gives up acetic acid and chromyl chloride, and it is also decomposed by water. By treating the mother liquors from the above preparation with hydrochloric acid a compound, BaCl(CrO3Cl), is obtained, and if the acid is dilute the compound contains 2 molecules of water and forms golden-yellow, hygroscopic needles.
