Heat of Solution The Heat of Solution is the amount of heat energy absorbed (endothermic) or released (exothermic) when a specific amount of solute dissolves in a solvent.
Steps in Solution Formation H 1 Step 1 - H 1 Step 1 - Expanding the solute Separating the solute into individual components
Steps in Solution Formation H 2 Step 2 - H 2 Step 2 - Expanding the solvent Overcoming intermolecular forces of the solvent molecules
Steps in Solution Formation H 3 Step 3 - H 3 Step 3 - Interaction of solute and solvent to form the solution
