Concept explainers
Interpretation:
Each of the given species are to be classified as acidic, basic, or amphoteric.
Concept Introduction:
Elements combine with oxygen atom(s) to form oxides. They, then, react with water to either produce an acid or a base.
In their low oxidation number, all alkali and alkaline metal oxides are basic in nature.
Some metal oxides, in a high oxidation state, show acidic behavior.
All nonmetal oxides are acidic in nature in their highest oxidation state. They are considerably neutral in their low oxidation state. In any case, nonmetal oxides do not show a basic nature.
Metallic oxides show acidic as well as basic natures, according to the reaction conditions. These are called amphoteric oxides.
