Why can aqueous solutions of non-metal oxides often turn blue litmus red?
Answer and explanation
Correct answer: They can form acidic substances in water
The governing concept is the acidic nature of many non-metal oxides in water. Oxides such as carbon dioxide and sulfur dioxide react or dissolve in water to produce acidic solutions, which provide hydrogen ions and turn blue litmus red. Therefore option A is correct. B is chemically unrelated, C reverses the usual behaviour, and D is too absolute because several non-metal oxides dissolve or react with water.
