A rise in temperature during an acid–base reaction indicates what?
Answer and explanation
Correct answer: Release of heat
In an acid–base neutralisation reaction, hydrogen ions from the acid combine with hydroxide ions from the base to form water. This process commonly releases heat to the surroundings, so the measured temperature rises. Such a reaction is called exothermic. Therefore, option A is correct. The rise is not evidence of light absorption, salt vapour formation, or a complete absence of heat; in fact, heat is being liberated.
