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, copper(II) oxide reacts with hydrochloric acid: CuO + 2HCl → CuCl2 + H2O. Some metal oxides, such as aluminium oxide and zinc oxide, are amphoteric and react with both acids and bases, so “generally” is important. Nevertheless, the broad school-level classification is basic, making option B correct.
