Chapter 14 Solutions and Their Behavior

Chapter 14 Solutions and Their Behavior. Solutions. A solution is a homogeneous mixture of two or more substances in a single phase. By convention, the component present in largest amount is identified as the solvent and the other component(s) as the solute (s). Solutions.
