प्रश्न
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?
उत्तर
Bases react with non-metal oxides to form a salt and water.
Bases + Non-metal oxides Salt + Water
Example:
2NaOH(aq) + CO2 (g) → Na2 CO3 (aq) + H2O (l)
Here, sodium hydroxide (base) reacts with carbon dioxide (non-metal oxide) to give sodium carbonate (salt) and water.
This reaction shows that non-metal oxides are acidic in nature.
