What happens when bases react with non-metal oxides? Explain with the help of an example. What does this reaction tell us about the nature of non-metal oxides?

When a base reacts with non-metal oxide both neutralize each other resulting respective salt and water are produced. This confirms that non-metal oxides are acidic in nature. Example-Sodium hydroxide gives sodium carbonate and water when it reacts with carbon dioxide.

2NaOH + CO₂⇨ Na₂CO₃ + H₂O
