What is the general nature of metal oxides?
Answer and explanation
Correct answer: Basic
The governing concept is the usual basic character of metal oxides. Many metal oxides react with acids in a neutralisation reaction to form a salt and water; for example, CuO + 2HCl → CuCl₂ + H₂O. This acid-consuming behaviour identifies CuO as a basic oxide. Therefore option B is correct. Acidic describes many non-metal oxides, neutral is not the general classification, and “sweet” is not a chemical nature.
