CHEM 100 Chapter Notes - Chapter 7: Solution, Solvation, Miscibility
Document Summary
7. 1 general aspects of solution formation. Solute the substance in smaller amount; dissolved in the solvent. Solvent the substance in larger amount. Mixtures have no fixed recipe, so the components can be present in varying proportions. Gas mixtures are an exception to this general rule. Solvent and solute can be mixed in any proportions in all gas mixtures. Miscible when two or more substances can form solutions in all proportions. By mixing two states at a time, nine kinds of mixtures, but only seven kinds of solutions are possible. The pairs of states that cannot be combined to form true solutions are solids in gases (s/g - smoke) and liquids in gases (l/g mists or fogs). Suspension consists of visible aggregates or particles suspended in a continuous medium. 7. 2 molecular properties and solution formation. The molecules of solvent and solute must interact through secondary forces to form a solution.
