The monohydrate (x = 1), known as baryta or baryta-water, is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form. See more Barium hydroxide can be prepared by dissolving barium oxide (BaO) in water: BaO + H2O → Ba(OH)2 It crystallises as the octahydrate, which converts to the monohydrate upon heating in air. At 100 °C in … See more Barium hydroxide decomposes to barium oxide when heated to 800 °C. Reaction with carbon dioxide gives barium carbonate. Its aqueous solution, being highly alkaline, undergoes neutralization reactions with acids due to it being a strong base. It is especially useful on … See more • Baralyme See more Industrially, barium hydroxide is used as the precursor to other barium compounds.
