Barium Uranate, BaUO4, is formed by fusing together barium chloride and urano-uranic oxide, or by mixing solutions of barium chloride and uranyl chloride and passing in excess of ammonia. The reaction in the latter case proceeds according to the equation:
UO2Cl2 + BaCl2 + 4NH3 + 2H2O = BaUO4 + 4NH4Cl.
It yields yellow glistening crystals, insoluble in water, but readily soluble in dilute hydrochloric acid. |
