Give a chemical reaction to prove that non-metallic oxides are acidic in nature.

Consider the following reaction,



Here, calcium hydroxide (Ca(OH)2) is a base, and it reacts with carbon dioxide (CO2) to give salt (calcium carbonate) and water. Comparing the above reaction with,


Base + Acid Salt + Water


one can see that CO2 acts as an acid. Hence, one can prove that non-metallic oxides are acidic in nature.
