Why is carbon dioxide considered an acidic oxide?
Answer and explanation
Correct answer: It can react with bases to form carbonates
An acidic oxide is identified by its reaction with bases and, in many cases, by its ability to form an acid with water. Carbon dioxide is a non-metal oxide; it reacts with sodium hydroxide to produce sodium carbonate and water: CO₂ + 2NaOH → Na₂CO₃ + H₂O. Hence option A is correct. Turning red litmus blue indicates a base, and the other choices misidentify carbon dioxide.
