### gray-white solid:

Barium peroxide
* gray-white solid.
* is another peroxide
  - barium
+ Barium peroxide, Properties: Barium compounds
  * Barium peroxide is a gray-white solid. It reacts with water to make oxygen gas. When it is heated very hot, it releases oxygen and turns into barium oxide.
+ Peroxide: Chemical compounds
  * Peroxide' is an ion. Peroxide can be a reducing agent or an oxidizing agent. More often it is an oxidizing agent. It can be reduced to oxide or oxidized to oxygen. Hydrogen peroxide is the most common peroxide. Barium peroxide is another peroxide.
