Question

Quizplus · Accepted Answer

The dissolution of an ionic solid in water being exothermic means that the process releases energy. This occurs when the energy released during the hydration of the ions (hydration energy) is greater than the energy required to break the ionic bonds in the solid (lattice energy).
