What is the best reason for considering non-metal oxides as acidic oxides?
Answer and explanation
Correct answer: They react with bases to form salt and water
The governing concept is the acidic behaviour of many non-metal oxides. Such oxides react with bases to form salt and water, just as acids do. For example, carbon dioxide reacts with calcium hydroxide: CO₂ + Ca(OH)₂ → CaCO₃ + H₂O. Some non-metal oxides may also form acids with water, but insolubility and hydrogen release are not general defining properties. Therefore option A is correct.
