BARIUM HYDROXIDE

Barium hydroxide is an inorganic chemical compound that is not soluble in water. The monohydrate (x = 1), known as baryta, is one of the principal compounds of barium. This white powder monohydrate is the usual commercial form. It is not soluble in acetone and is corrosive to metals and tissues. It vapors pressures are temperature-dependent given as 0.48 kPa at 17.6 °C, 1.32 kPa at 32.1 °C, 2.36 kPa at 40.7 °C; 5.08 kPa at 50.7 °C. It is soluble in ether.

Its appearance is white to off-white crystals or granular form. Its crystalline structure is octahedral/monoclinic. It loses water of crystallization at above 70C. It rapidly absorbs carbon dioxide from the air, becoming incompletely soluble in water and methanol. It is also slightly sol in ethanol. It is soluble in acids.

Barium hydroxide monohydrate reacts with sodium hydroxide but is less soluble in water. It neutralizes acids to form salts plus water. This reaction is exothermic.

It has some uses.

• It also forms a strong caustic base in an aqueous solution. It is utilized as a test for sulfides.
• Use of barium hydroxide lime rather than soda-lime, high sevoflurane concentration, high absorbent temperature, and fresh absorbent use.
• I served in the manufacture of alkalis, glass, oil, and grease additives.
• It aids in the manufacture of barium soaps, and other barium compounds.
• It works as an alkalizing agent in water softening and sulfate removal agent in water and brine treatment.
• It is used in insecticides and fungicides.
