Why are non-metal oxides generally considered acidic?
Answer and explanation
Correct answer: They behave like acidic oxides with water or bases
An acidic oxide generally forms an acidic solution with water or reacts with a base to form salt and water. Many non-metal oxides show one or both of these behaviours; for example, carbon dioxide dissolves in water to form carbonic acid and reacts with bases to produce carbonates. Hence they are generally classified as acidic oxides. Option C describes a basic effect, while B and D make absolute claims that are not chemically valid for all non-metal oxides.
