What is the general nature of non-metal oxides?
Answer and explanation
Correct answer: Acidic
The governing concept is the general acidic character of non-metal oxides. Many of them react with water to form acids; for example, CO₂ + H₂O → H₂CO₃, and SO₂ + H₂O → H₂SO₃. They can also react with bases to form salts and water. Hence option A is correct. Basic is the usual description for many metal oxides, while metallic and salty are not appropriate general classifications of oxides.
