What is the general nature of metal oxides?

Answer and explanation

Correct answer: Basic

Most metal oxides are basic because they react with acids to form salt and water; for example, CuO + 2HCl → CuCl₂ + H₂O. This acid-neutralising behaviour supports option B. Some metal oxides, such as aluminium oxide and zinc oxide, are amphoteric and react with both acids and bases, so “generally” is important. Acidic oxides are more commonly associated with non-metals, while sweetness is not a chemical classification.
