What is the general nature of metal oxides?

Answer and explanation

Correct answer: Basic

Most metal oxides are basic oxides. They commonly react with acids in a neutralisation reaction to form salt and water; for example, CuO + 2HCl → CuCl₂ + H₂O. This acid-neutralising behaviour supports option B. “Acidic” is generally associated with many non-metal oxides, while neutral and salty do not describe the usual chemical nature of metal oxides.
