उत्तर
Bases react with non-metal oxides to form salt and water.
\[\ce{Non-metal oxide + Base -> Salt + Water}\]
Calcium hydroxide is a base, and carbon dioxide is a non-metal oxide. So, calcium hydroxide solution reacts with carbon dioxide to produce calcium carbonate and water.
\[\ce{\underset{(Base)}{\underset{Calcium hydroxide}{Ca(OH)2_{(aq)}}} + \underset{(Non-metal oxide)}{\underset{Carbon dioxide}{CO2_{(g)}}} -> \underset{(Salt)}{\underset{Calcium carbonate}{CaCO3_{(s)}}} + \underset{Water}{H2O_{(l)}}}\]
The reactions of non-metal oxides with bases to form salt and water show that non-metal oxides are acidic in nature.
