Question

Define the term.

Oxides

Answer 1

An oxide is a category of chemical compound that has one or more oxygen atoms as well as another element in its composition such as Li₂O, CO_2, H₂O, etc

Classification of oxides-

• Non-metallic oxides (acidic oxides)- Oxides of non-metals are called non-metallic oxides.
• They are acidic oxides and react with water to produce an acid that turns blue litmus red.
• Example- Carbon dioxide(CO₂), Sulphur dioxide(SO₂), etc.

• Metallic oxides (basic oxides)- Oxides of metals are called metallic oxides.
• They are basic oxides and react with water to produce a base that turns red litmus blue.
• Example- Sodium oxide(Na₂O), Potassium oxide(K₂O), etc.

• Amphoteric oxides- Oxides that show the property of acidic oxides as well as basic oxides.
• Example- Zinc oxides(ZnO), Aluminum oxides(Al₂O₃), etc.

• Neutral oxides- Oxides that show neither the properties of acidic oxides nor the basic oxides.
• Example- Water(H₂O), Carbon monoxide(CO), etc.
