Barium hydroxide 8-water, impor

Barium hydroxide (hydrated baryta) — one of complex non - organic substances. Is the strong basis.
Chemical formula — Ba(OH)2. Barium hydroxide at reference conditions represents colourless crystals. Saturated solution of barium hydroxide is called baryta water. It is hygroscopic. It is not soluble in alcohol, but is soluble in water.
Forms crystalline hydrates with one, two, seven and eight water molecules. Barium hydroxide is toxic, maximum concentration limit makes 0,5 mg/m ³. Apply barium hydroxide as reactant on (SO4)2− and (CO3) 2− (sulfate - and carbonate ions), to purification of rastititelny oils and animal fats as component of greasings, for removal (SO4)2− (sulfate ions) of industrial solutions, receiving salts of barium, and also rubidium hydroxides and caesium from their sulfates and carbonates.
In sugar industry it is applied to release of sugar from molasses.
