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?
Barium Hydroxide [Ba(OH)₂ & Ba(OH)₂·8H₂O] - Applications and Uses
Barium Hydroxide, available in both its anhydrous and octahydrate forms, is a versatile and reactive alkali with significant utility across industrial, laboratory, and chemical synthesis sectors. Its strong basicity and unique reactivity with anions like sulfate and carbonate make it a valuable processing agent and chemical precursor.
Primary Applications and Industries:
1. Chemical Synthesis & Industrial Precursor
Barium Hydroxide serves as a fundamental starting material for the production of a wide range of other barium compounds.
* Barium Salts: It is the primary raw material for manufacturing various barium salts, including barium chloride, barium nitrate, and barium stearate.
* Organic Synthesis: Used extensively in the production of barium-based organic compounds, which act as catalysts or stabilizers in the plastics and rubber industries.
2. Industrial Process & Treatment Agent
Its chemical properties are leveraged for purification, conditioning, and remediation in numerous processes.
* Water Treatment & Softening: Effectively removes sulfate and carbonate anions from water streams in industrial settings, preventing scale formation in boilers and cooling systems.
* Dehydration Agent: The monohydrate form is particularly effective at dehydrating various organic liquids and removing trace water from products.
* Sugar Refining: Used in the purification process of sugar to remove impurities.
* Grease and Oil Industry: Acts as a saponification agent in the fixation and modification of animal and vegetable oils for grease production.
3. Laboratory & Analytical Chemistry
In the laboratory, Barium Hydroxide is valued for its precise analytical capabilities.
* Titration of Weak Acids: Its strong base strength makes it an excellent reagent for the titration of weak acids, especially organic acids, providing a sharp endpoint.
* Reagent for Carbon Dioxide (CO₂): Used as a sensitive reagent to detect and absorb CO₂, as it forms insoluble barium carbonate.
4. Manufacturing & Additive Applications
* Glass & Ceramics: An additive in the manufacture of certain types of glass and ceramic glazes, improving luster and durability.
* Synthetic Rubber: Serves as a vulcanizing agent in the production of synthetic rubber, enhancing its mechanical properties.
* Pesticides & Corrosion Inhibitors: A key component in the formulation of specific pesticides and industrial corrosion inhibitors.
