Barium hydroxide, a chemical compound with the chemical formula Ba(OH)2, is white solid substance, soluble in water, the solution is called barite water, strong alkaline. Barium Hydroxide has another name, namely: caustic barite, barium hydrate. 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. Barium Hydroxide Octahydrate, as a highly water insoluble crystalline Barium source, is an inorganic chemical compound that is one of the most dangerous chemicals used in the laboratory. Ba(OH)2.8H2O is a colorless crystal at room temperature. It has a density of 2.18g / cm3, water soluble and acid, toxic, can cause damage to the nervous system and digestive system. Ba(OH)2.8H2O is corrosive, may cause burns to eye and skin. It may cause digestive tract irratation if swallowed. Example Reactions: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3

What are Barium Hydroxide and Barium Hydroxide Octahydrate used for?
Industrially, barium hydroxide is used as the precursor to other barium compounds. The monohydrate is used to dehydrate and remove sulfate from various products. As laboratory uses, Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. Barium hydroxide octahydrate is extensively used in the manufacturing of barium salts and barium organic compounds; as an additive in the petroleum industry; In manufacture of alkali, glass; in synthetic rubber vulcanization, in corrosion inhibitors, pesticides; boiler scale remedy; Boiler cleaners, in the sugar industry, fix animal and vegetable oils, soften water, make glasses, paint the ceiling; Reagent for CO2 gas; Used for fat deposits and silicate smelting.
