• Consider NaCl (solute) dissolving in water (solvent) – the water hydrogen-bonds have to be interrupted – NaCl dissociates into Na + and Cl - – ion-dipole forces form: Na +… δ -OH 2 and Cl -… δ +H 2 O – We say the ions are solvated by water – If water is the solvent, we say the ions are hydrated The Solution Process The Solution Process + H 2 O

Energy Changes and Solution Formation • There are three energy steps in forming a solution: – separation of solute molecules ( H 1 ) – separation of solvent molecules ( H 2 ) – formation of solute-solvent interactions ( H 3 ) • We define the enthalpy change in the solution process as H soln = H 1 + H 2 + H 3 H soln can either be positive or negative depending on the intermolecular forces The Solution Process The Solution Process
