baariumperoksiid

Barium peroxide is a chemical compound with the formula BaO2. It is a white solid that is slightly soluble in water. Barium peroxide is an oxidizing agent and can react with combustible materials to cause fires. It is also a strong irritant to the skin and eyes.

Barium peroxide is produced industrially by heating barium oxide in the presence of oxygen. The reaction is as follows: 2BaO + O2 -> 2BaO2. It can also be prepared by passing chlorine gas through a suspension of barium hydroxide in water.

Barium peroxide has a number of uses, including as a bleaching agent, a component in pyrotechnics, and as a source of oxygen in some chemical reactions. It is also used in the production of other barium compounds. In dentistry, it has been used as a component in some tooth-whitening products, though its use in this application has declined due to safety concerns.

When heated to high temperatures, barium peroxide decomposes to form barium oxide and oxygen: 2BaO2 -> 2BaO + O2. This decomposition reaction can be used to generate oxygen in a controlled manner.

Barium peroxide is considered a hazardous substance and should be handled with care. It is important to wear appropriate personal protective equipment, such as gloves and eye protection, when working with this compound. In case of contact, the affected area should be washed immediately with plenty of water.
