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[edit]
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[edit]
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[edit]
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[edit]
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.
