Barium hydroxide (caustic barium, hydroxide of barium, barium hydroxide) Ba(OH)2·8H2O - colorless crystals. Barium hydroxide is highly soluble in water (3.75% of anhydrous Ba(OH)2 at 20 °C), solubility increases when heated. The solution has a strong alkaline reaction. In contact with air, it absorbs CO2 and becomes cloudy due to formation of insoluble BaCO3. When drying over concentrated H2SO4 barium hydroxide is easy to lose 7 molecules of water of crystallization, complete dewatering is achieved only at 120-150 °C. Melt crystallization in water at 78 °C.
