Document Summary
Thirsty solutions: why you shouldn"t drink seawater (p. 544) Solution equilibrium and factors affecting solubility (p. 555) Colligative properties: vapor pressure lowering, freezing point depres sion, boiling point elevation, and osmotic pressure (p. 567) Colligative properties of strong electrolyte solutions (p. 579) A solution is a homogeneous mixture of two or more substances. In a solution, the majority component is the solvent and the minority component is the solute. The tendency toward greater entropy (or greater energy dispersal) is the driving force for solution formation. In aqueous solutions, water is a solvent, and a solid, liquid, or gas is the solute: solubility and energetics of solution formation (12. 2, 12. 3) The solubility of a substance is the amount of the substance that will dissolve in a given amount of solvent. The solubility of one substance in another depends on the types of intermolecular forces that exist between the substances as well as within each substance.
