Solutions

8.1. Characterize the dissolving process.
8.2. Characterize solutions as strong electrolytes, weak electrolytes, and nonelectrolytes.
8.3. describe the macroscopic observations when pairs of liquids are mixed together.
8.4. list a set of rules for predicting whether a molecule is polar or nonpolar.
8.5. describe the intermolecular attractive forces; dipole-dipole, hydrogen-bonding and dispersion forces.
8.6. describe the interactions responsible for determining whether a particular solute solvent pair will form a homogeneous mixture or a heterogeneous mixture.
8.7. describe how an energy analysis of the attractive interactions lead to exothermic or endothermic enthalpies (DH° solution) of solution.
8.8. define the terms; solubility, unsaturated, saturated and supersaturated.
8.9. list the important criteria for predicting whether a mixture will be homogeneous or heterogeneous when mixing a solid and a liquid.
8.10. define the term lattice energy and explain its importance in the enthalpy of solution.
8.11. define the concentration terms; weight percent, mole fraction, molarity, and molality and use these concentration expressions to determine the concentration of any homogeneous mixture.
8.12. define the term colligative property and list those physical properties of a solution which can be classified as colligative properties.
8.13. explain how the vapor pressure of a liquid solvent in a solution is affected by the presence of a solute.
8.14. write the mathematical equation which relates the vapor pressure of the solution to the concentration of the solute and the vapor pressure of the solvent.
8.15. explain how and why the freezing point and the boiling point of a liquid are affected by the addition of a nonvolatile solute.
8.16. write and use the mathematical equation that describes the dependence of the freezing point or boiling point on the concentration of solution.
