Carbon dioxide is considered what type of oxide?
Answer and explanation
Correct answer: Acidic oxide
Carbon dioxide, CO₂, is an oxide of carbon, and carbon is a non-metal. It is classified as an acidic oxide because it reacts with water to form carbonic acid: CO₂ + H₂O ⇌ H₂CO₃. It also reacts with bases such as lime water. Therefore option B is correct. It is not a basic oxide, a metal oxide or a salt; those choices conflict with its composition and reactions.
