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.
- 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
- 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.
