Question

What happens when a non-metallic oxide is added to a base? Give the chemical equation involved.

Answer 1

When a non-metallic oxide is added to a base, they undergo a neutralisation reaction to form a salt and water.

Example: Carbon dioxide reacts with calcium hydroxide to form calcium carbonate and water:

\[\ce{CO2 + Ca(OH)2 -> CaCO3 + H2O}\]

Here, CO₂ is a non-metallic oxide and Ca(OH)₂ is a base.
