Which conclusion is correct for the reaction between a non-metal oxide and a base?
Answer and explanation
Correct answer: Salt and water may be formed
The governing concept is the acidic nature of many non-metal oxides. Such oxides can react with bases in a neutralisation-type reaction to form a salt and water. For example, CO₂ + 2NaOH → Na₂CO₃ + H₂O, while CO₂ with limewater can form calcium carbonate. Hydrogen gas and a metal are not compulsory products, and it is incorrect to say that no reaction ever occurs. Therefore, option A is correct.
