Product Name:Barium hydroxide
CAS Number:17194-00-2
Molecular formula:BaH2O2
Molecular Weight:171.34

Barium 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.
