Peroxides refer to compounds formed by oxygen and other elements, where oxygen carries a charge of -2. From the chemical formula, both peroxides and oxides contain oxygen, but their charge states of oxygen are different. The oxygen element in the oxide has a charge of -2, while the oxygen element in the peroxide has a charge of -1.
Peroxide refers to an oxide containing two oxygen atoms, where the oxygen element carries a charge of -1. For example, hydrogen peroxide, benzoyl peroxide, etc. Oxides are mainly used for the preparation of other compounds or as inorganic materials, while peroxides and oxides are two different compounds with different chemical properties, structures, and uses.
1. Different structure: the Chemical bond between the two oxygen atoms contained in the peroxide is more relaxed and easily broken than the Chemical bond between the oxygen atoms in the oxide, so the decomposition rate of the peroxide is faster than that of the oxide.
2. Different chemical properties: Peroxides have more active chemical properties than oxides, easily decomposing to produce free radicals, and have strong oxidizing and reducing properties. For example, hydrogen peroxide can react with metals to produce oxygen and water. Although they all contain oxygen, the charge state of oxygen is different, so their properties are different. Therefore, although peroxides and oxides have similarities, they are two different compounds.
3. Different uses: Peroxides have strong oxidizing and reducing properties and are widely used in bleaching, disinfection, oxidants, and other fields. For example, iron oxide, zinc oxide, etc.
