Barium Hydroxide Octahydrate is an inorganic barium compound with the chemical formula Ba(OH)₂·8H₂O. It is the octahydrate form of barium hydroxide and appears as colorless or white, odorless crystals that are highly soluble in water. The compound consists of barium ions (Ba²⁺), hydroxide ions (OH⁻), and eight molecules of water of crystallization. It is stable under normal storage conditions but is incompatible with strong acids, oxidizing agents, and chlorinated rubber. Barium hydroxide octahydrate is a high purity and strong alkaline nature, widely used as a laboratory reagent and important intermediate in inorganic chemical synthesis.
CAS No.: 12230-71-6
Synonyms: Barium dihydroxide octahydrate, Dihydroxybarium octahydrate.

Barium Hydroxide Octahydrate is used in chemical synthesis, analytical chemistry, production of lubricating grease, manufacturing of soap, refining of sugar and as a precursor for the preparation of various barium compounds.
The chemical formula for barium hydroxide octahydrate is Ba(OH)₂·8H₂O. This means there is one molecule of barium hydroxide with eight molecules of water of crystallisation.
Barium Hydroxide Octahydrate is a basic metal hydroxide containing bound water molecules, while Ammonium Thiocyanate is an ammonium salt containing sulfur, carbon and nitrogen. They are different in their chemical formula, structure and physical properties in a fundamental way. They are famously combined in chemistry laboratories to demonstrate a rapid endothermic reaction.
Barium Hydroxide Octahydrate is usually produced by reacting barium oxide or barium sulfide with water, followed by crystallization to obtain the hydrated octahydrate form.
