Frequently When Salts Dissolve in Water, the Solution Becomes Warm

question 57

Essay

Frequently when salts dissolve in water, the solution becomes warm. Such a process is exothermic. When other salts, such as ammonium chloride, dissolve in water, the solution becomes cold, indicating an endothermic process. Because endothermic processes are generally not spontaneous, why does ammonium chloride dissolve in water?
