Oxides. Classification of oxides, their names, production methods. Properties and applications of oxides.

Oxide is a binary compound of a chemical element with oxygen.
Classification.
Salt-forming oxides:
basic oxides (for example, sodium oxide Na2O, copper (II) oxide CuO).
acidic oxides (e.g. sulfur oxide (VI) SO3, nitrogen oxide (IV) NO2).
amphoteric oxides (for example, zinc oxide ZnO, aluminum oxide Al2O3).
Non-salt-forming oxides: carbon oxide (II) CO, nitrogen oxide (I) N2O, nitrogen oxide (II) NO, silicon oxide (II) SiO.
1. Interaction of simple substances with oxygen.
2. Roasting or combustion of binary compounds in oxygen.
3. Thermal decomposition of salts.
4. Thermal decomposition of bases or acids.
5. Oxidation of lower oxides to higher ones and restoration of higher ones to lower ones.
6. Interaction of some metals with water at high temperatures.
Oxides are a very common type of compounds found in the earth’s crust and in the universe in general. Examples of such compounds are rust, water, sand, carbon dioxide, a number of dyes.
