Oxides are compounds of oxygen with other elements, and are amongst the most important of the classes of chemical compounds. Basic oxides and acid oxides are described in the article CHEMISTRY (q.v.). In addition to these two large classes of oxides there are numerous oxides which do not possess either basic or acid properties, or if at all only to a very insignificant degree.
