The acid–base properties of the given chromium oxides are to be determined. Concept Introduction: Elements combine with oxygen atom(s) to form oxides. They then react with water to produce either acid or base. In their lowest oxidation number, all alkali and alkaline earth metal oxides are basic in nature. Some metal oxides in 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 basic nature. Some metallic oxides show both acidic as well as basic nature according to the reaction conditions. These metallic oxides are called amphoteric oxides.
