过氧化物，由于分子中含有过氧基或过氧离子而得其名。此外具有极弱酸性的过氧化氢与碱作用也可生成过氧化物。因此，过氧化物也可看作是过氧化氢的盐。能生成过氧化物的金属，主要是碱金属和碱土金属。
Pge.75ix.comdugebang.75ix.comeroxide is named for its peroxide group or peroxide ion in the molecule. In addition, hydrogen peroxide with very weak acidity can react with alkali to form peroxide. Therefore, peroxide can also be regarded as a salt of hydrogen peroxide. Metals that can produce peroxides are mainly alkali metals and alkaline earth metals.
过氧化钠过氧化钠是钠在氧气或空气中燃烧的产物之一，纯品过氧化钠为白色，但一般见到的过氧化钠呈淡黄色，原因是反应过程中生成了少量超氧化钠。过氧化钠易潮解、有腐蚀性，应密封保存；具有强氧化性，可以用来漂白纺织类物品、麦杆、羽毛等。
Sodium peroxide is one of the products of sodium combustion in oxygen or air. The pure sodium peroxide is white, but the commonly seen sodium peroxide is pale yellow, because a small amount of sodium superoxide is produced in the reaction process. Sodium peroxide is easy to be deliquescent and corrosive, and should be sealed and preserved. It has strong oxidation and can be used to bleach textile products, straw, feathers and so on.
