| Chemical Properties | Back Directory | [Description]
Barium hydroxide is available as colourless or white crystals. It is odourless and soluble
in water. It is stable under ordinary conditions of use and storage. It is incompatible with
acids, oxidisers, and chlorinated rubber. Barium hydroxide is corrosive to metals such
as zinc. Barium hydroxide is very alkaline and rapidly absorbs carbon dioxide from air,
becoming completely insoluble in water. Barium hydroxide is used in analytical chemistry
for the titration of weak acids. Barium hydroxide is used in organic synthesis as a strong
base. Barium hydroxide decomposes to barium oxide when heated to 800°C. | [Appearance]

Catalyst in organic synthesis.
| [Uses]
In manufacture of alkali, glass; in synthetic rubber vulcanization, in corrosion inhibitors, pesticides, sugar industry; boiler scale remedy; refining animal and vegetable oils; softening water. Catalyst in organic synthesis. | [Application]
Catalyzes the β-elimination of phosphoserine residues.
Resin stabilizer; manufacture of oil and grease additives; raw material of pigment; sulfate removal agent. | [Purification Methods]
It crystallises from water (1mL/g) and readily absorbs CO2 from air. It effloresces to the monohydrate. It dehydrates to Ba(OH)2 in dry air at 100o. An aqueous solution (baryta water) absorbs CO2 to form a white precipitate of BaCO3. |
