Barium peroxide

Barium Peroxide is an inorganic compound with the chemical formula BaO2. This white solid (which is often found as a grayish or yellowish powder due to the presence of impurities) is one of the most common inorganic peroxides, and it was the first peroxide compound discovered.

Chemistry

Barium peroxide is a peroxide, a compound containing an oxygen-oxygen single bond. The term 'peroxide' can also refer to compounds in which peroxide groups are bonded to a metal. The O-O group in a peroxide is called the peroxide group or peroxo group. In contrast to oxides, which are compounds that contain oxygen with a state of oxidation of -2, peroxides are defined as compounds containing oxygen with a state of oxidation of -1.

Preparation

Barium peroxide is produced by the reaction of barium oxide (BaO) with oxygen at temperatures above 500 °C. The reaction is reversible and the forward reaction is favored at high temperatures, while the reverse reaction is favored at low temperatures.

Uses

Barium peroxide is used in the production of hydrogen peroxide and other peroxides. It is also used as a bleaching agent, in the manufacture of glass and ceramics, and in the preparation of other barium compounds.

Safety

Barium peroxide is a strong oxidizer and can react violently with combustible and reducing materials. It is also toxic if ingested or inhaled, and can cause irritation to the skin and eyes.
