Barium hydroxide

Barium Hydroxide is a chemical compound with the formula Ba(OH)2. It is a white crystalline solid that is odorless and insoluble in water. It is one of the strongest known alkaline substances.

Chemical Properties

Barium hydroxide is a strong base, meaning it has a high affinity for protons and readily accepts them to form water and a barium ion. It is also a strong electrolyte, meaning it readily dissociates into its ions in solution, which allows it to conduct electricity.

Preparation

Barium hydroxide can be prepared by dissolving barium oxide (BaO) in water. This reaction is exothermic, meaning it releases heat. The resulting solution is a saturated solution of barium hydroxide.

Uses

Barium hydroxide is used in a variety of applications. It is used in the preparation of other barium compounds, as a catalyst in organic synthesis, and in the manufacture of glass and ceramics. It is also used in the neutralization of acids.

Safety

Barium hydroxide is a hazardous substance. It is corrosive and can cause burns if it comes into contact with skin or eyes. It is also toxic if ingested or inhaled.
