PreparationBarium hydroxide is made by dissolving barium oxide in hot water. The octahydrate, Ba(OH)2?8H2O, crystallizes upon cooling. It also is prepared by precipitation with caustic soda from an aqueous solution of barium sulfide: BaS + 2NaOH → Ba(OH)2+ Na2S. ...

After gelation they were C?vered with a top solution prepared by dissolving 10 g ,:nlver chloride in 50 ml. ammonium hydroxide (8.33 normal). After 10 to 12 days crystals of up to 5-8 mm in edge were obtained. Most of the crystals wore octa- hedral or truncated tetrahedral forms. ...
Air & Water ReactionsBarium carbonate is insoluble in water and soluble in most acids, with the exception of sulfuric acid. Reactivity ProfileSalts, basic, such as Barium carbonate, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH...
