Document Summary

Only (not all sections of chapter, only readings. Mixtures called suspensions have larger particles than colloids; not truly homogenous because their particles separate on standing and are visible with a low-power microscope. For solutions in which a gas or solid is dissolved in a liquid, the dissolved substance is called the solute and the liquid is called the solvent. When one liquid is dissolved in another, minor component is usually considered solute, and major component is the solvent. Chapter 12. 2: energy changes and the solution process. Situation more complex for solutions than pure substances, because three types of interactions among particles have to be taken into account: solvent-solvent, solvent-solute, solute-solute. Like dissolves like solutions will form when the three types of interactions are similar in kind and in magnitude. Dissolution of a solute in a solvent has an associated free-energy charge, g = h t s, whose value describes its spontaneity.
