When ammonium nitrate is dissolved in water, it produces an endothermic reaction, i.e. energy is taken in by the system from its surroundings in the form of heat. When the nitrate ion is separated from the ammonium ion by the polar water molecules, an endothermic reaction takes place.

However, when the separated ions become hydrated in the solution, an exothermic reaction reaction takes place - heat is given off, instead of absorbed. But since more energy is required to separate the ions than to hydrate these ions, the overall reaction is indeed endothermic.

The same thing happens when ammonium chloride is dissolved in water. The endothermic separation of the ions will dictate the overall reaction, since the exothermic hydration of the ions will gfive off less energy. As a result, dissolving ammonium chloride in water will be an endothermic process
