Why are metal oxides generally considered basic?
Answer and explanation
Correct answer: They react with acids to form salt and water
The governing concept is the general basic character of many metal oxides. A basic oxide reacts with an acid in a neutralisation reaction to form salt and water; for example, CuO + 2HCl → CuCl2 + H2O. Some metal oxides also react with water to form hydroxides. Therefore option A gives the defining reason. Option B describes acidity, while C and D are factually incorrect generalisations.
