A non-metal oxide dissolves in water and forms a solution that turns blue litmus red. What type of oxide is it?

Answer and explanation

Correct answer: Acidic oxide

Blue litmus turning red is the characteristic test for an acidic medium. If a non-metal oxide dissolves in water and produces such a solution, the oxide has formed an acid, for example SO₂ + H₂O → H₂SO₃ or CO₂ + H₂O ⇌ H₂CO₃. This is why many non-metal oxides are classified as acidic oxides. Basic oxides would turn red litmus blue, while a neutral salt or metallic base does not fit the observation. Thus A is correct.
