Question
What is the nature of the reaction when an acid or a
base is dissolved in water?Solution
Dissolving an acid or a base in water is typically an exothermic process, where heat is released. This is particularly notable with strong acids and bases, which can release a significant amount of heat, potentially posing hazards such as boiling or splattering if not handled carefully. This heat release is a result of the exothermic nature of the hydration process of the ions.
