What is formed when an acid reacts with a metal oxide?
Answer and explanation
Correct answer: Salt and water
Most metal oxides are basic oxides, so they react with acids in a neutralisation reaction. The products are a salt and water; for example, copper(II) oxide reacts with hydrochloric acid to form copper(II) chloride and water. Therefore, option A is correct. Hydrogen gas is usually associated with the reaction of an acid with a reactive metal, not with a metal oxide, and oxygen gas is not the general product.
