2 The Main Point To understand the process by which one substance dissolves in another to form a homogenous mixture (solution). Predict the properties of homogeneous mixtures. Terminology of solutions Role of intermolecular forces and “ l ike dissolves like” Enthalpies of solution Hydrophobicity and hydrophilicity Concentration units Effects of pressure and temperature on solubility Colligative Properties Vapor pressure lowering Boiling point elevation Freezing point depression Osmotic pressure Chapter 13 The Properties of Mixtures
