What type of oxides are formed when nonmetals combine with oxygen?


When non-metals react with oxygen, they form oxides which are either acidic or neutral in nature.

For example, 


  1. Acidic Oxide

Carbon +Oxygen → Carbon Dioxide

C(s) + O 2 (g)  → CO 2 (g)

  • Carbon Dioxide dissolves in water to form Carbonic Acid.
  • So, Carbon Dioxide is acidic in nature


  1. Neutral Oxide

Carbon reacts with Oxygen in an insufficient supply of air to produce Carbon Monoxide .

Carbon +Oxygen → Carbon Monoxide

C (s) + ½ O 2 (g) → CO (g)

  • It does not react with water.
  • So, it produces neither acid nor base with water .

Therefore, carbon monoxide is neutral.
