Question

249. Treating alkalis with acidic oxides:
(b) Ca(OH)₂ + CO₂ 🡪

Open in App

Solution

Acidic oxides are non-metal oxides.
When a base reacts with non-metal oxides, they neutralize each other and form salt and water.
When calcium hydroxide reacts with carbon dioxide, it will form calcium carbonate and water.
The chemical equation for the given reaction is as follows:
Ca(OH)₂ + CO₂ 🡪 CaCO₃ + H₂O
calcium hydroxide carbon dioxide calcium carbonate water
