What is the formula for barium hydroxide?

The chemical formula for barium hydroxide is Ba(OH)2. It is a chemical compound that consists of one barium ion (Ba2+) and two hydroxide ions (OH-) bonded together.

Barium hydroxide is a white, odorless, and hygroscopic solid at room temperature. It is highly soluble in water and forms a strong alkaline solution.

Barium hydroxide is commonly used in the production of various barium compounds, as a pH regulator in water treatment, and in the manufacturing of glass, ceramics, and lubricating oils.

When heated, barium hydroxide undergoes thermal decomposition to form barium oxide (BaO) and water vapor. It has a molar mass of 171.35 g/mol and a density of 3.74 g/cm3.

Barium hydroxide should be handled with care as it is a corrosive substance that can cause skin and eye irritation. It should be stored in a cool, dry place away from incompatible substances.
