In farther chem studies, you will learn more information about thermodynamics and how bond breaking (breaking attractive forces) is endothermic, while making a bond (generating attractive forces) is exothermic. The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive forces being broken (endothermic) and the attractive forces being made (exothermic). Based on your results for your ionic solid dissolving, which forces are stronger and briefly explain how this leads to either an exothermic or an endothermic reaction.
