decomposed by water and acids. Of the commonly used barium salts, barium chloride BaCl2, and other halides, the nitrate Ba(NO3)2, the sulfide BaS, and the chlorate Ba(CIO3)2are highly soluble; barium sulfate BaSO4, barium carbonate BaCO3, and barium chromate BaCrO4are poorly soluble. ...
Barium chloride is a white color solid that has a density of 3.856 g mL-1. The melting and the boiling points of the barium chloride are 962 °C and 1560 °C respectively. It is easily soluble in the water (H2O), methanol and is insoluble with the ethanol and the ethyl acetate. Its...
atmospheric CO2forming solid monohydrate; further heating produces anhydrous Ba(OH)2melting at 407°C; readily dissolves in water (3.76 g/100 g at 20°C and 11.7 g/100 g at 50°C); aqueous solution highly alkaline; also soluble in methanol; slightly soluble in ethanol; insoluble in acetone...
Barium sulfate is available as white powder or polymorphous crystals. It is stable, odor- less, insoluble, or negligibly soluble in water, and may produce sulfur oxides on burning. It occurs naturally as mineral barite (barytes). It has wide use as an inert i ller pigment extender in pain...
