A metal oxide reacts with an acid to form salt and water. Which nature does this show?
Answer and explanation
Correct answer: Basic nature
A base reacts with an acid in a neutralisation reaction to produce salt and water. Many metal oxides show this same behaviour; for example, CuO + 2HCl → CuCl2 + H2O. Therefore, the oxide displays basic nature and option B is correct. Acidic nature is associated with reactions characteristic of non-metal oxides, while radioactivity and volatility are unrelated properties.
