What is the general nature of non-metal oxides?
Answer and explanation
Correct answer: Acidic
Non-metal oxides are generally acidic. Many dissolve or react with water to form acids, and these acidic solutions can turn blue litmus red. For example, carbon dioxide reacts with water to form carbonic acid. Thus option B is correct. Basic describes the usual behaviour of metal oxides, while metallic and salt-free are not acid–base classifications for these oxides.
