Why are non-metal oxides called acidic oxides?

Answer and explanation

Correct answer: Because they can form acidic solutions with water

The governing classification is based on the acid-forming behaviour of many non-metal oxides. For example, carbon dioxide reacts with water to form carbonic acid: CO2 + H2O ⇌ H2CO3, while sulphur dioxide forms sulphurous acid. Their aqueous solutions can therefore show acidic properties. Option A is correct. Turning red litmus blue would indicate a base, and the other choices do not describe the defining reaction.
