Well, you are breaking strong chemical bonds....

Explanation:

So the dissolution reaction is likely to be endothermic. And in fact the dissolution of sodium chloride in water is very SLIGHTLY endothermic.....here the energy used to disrupt the sodium chloride lattice, is almost equal to the hydration energy released when the sodium and chloride ions are solvated. However, there are much better examples of endothermic and exothermic chemical reactions to choose.
