Objectives
• To explain the energy changes that occur during the dissolution of solids in liquids
• Associating the reactions with exothermic and endothermic heat exchange
• To calculate enthalpies of solution
• To calculate the heat released or absorbed by the system based on the temperature change of the surroundings
