What is Barium hydroxide octahydrate?
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.
Chemical properties
white crystalline powder

The Uses of Barium hydroxide octahydrate
Used in manufacture of alkali, glass; in synthetic rubber vulcanization, alkalizing agent in water softening, boiler scale remedy, softening water.Barium hydroxide octahydrate is used in the centromeric heterochromatin banding technique. It acts as a precursor to prepare barium titanate, barium sulfate, barium phosphate and barium sulfide. Further, it is used in analytical chemistry for the titration of weak acids especially organic acids. It is involved in the preparation of cyclopentanone, diacetone alcohol and D-Gulonic gamma-lactone. In addition to this, it finds application in ester hydrolysis such as dimethyl hendecanedioate and decarboxylation of amino acids.
What are the applications of Application
Barium hydroxide octahydrate is an agent used in the centromeric heterochromatin banding technnique
What are the applications of 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.
