Which statement shows that heat can be released in a neutralisation reaction?
Answer and explanation
Correct answer: The container feels warm when acid and base are mixed
Neutralisation is the reaction between an acid and a base, commonly producing salt and water. In many such reactions, energy is released as heat, so the reaction mixture or its container becomes warmer. This observation supports option A. Freezing, formation of no substance, and production of only metal are not the expected results of acid–base neutralisation, so options B, C and D are incorrect.
