Differentiate among acidic oxides, basic oxides, amphoteric oxides and neutral oxides.
Oxides
Oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula.
Acidic oxide | Basic oxide | Amphoteric oxide | Neutral oxide |
Acidic oxides are the oxides of non-metals. They dissolve in water to produce acids. | Basic oxides are the oxides of metals. They are usually insoluble in water. | Amphoteric oxides are metallic oxides that show both basic and acidic properties. | Neutral oxides show neither basic nor acidic properties. This means that they do not form salt while reacting with acids or bases. |
Acidic oxides turns blue litmus red. | Basic oxides turns red litmus blue. | Amphoteric oxide shows no change in litmus paper. | Neutral oxides do not affect litmus paper. |
