| Goal I. Extend the principles
of the kinetic-molecular theory to solutions. |
Objectives: To meet the requirements of Goal I,
you must be able to:
- describe the
solution process in terms of the kinetic-molecular theory and the
role of InterMolecular Forces (IMF) in the solution process.
- define the
terms miscible and immiscible; explain the
phrase “like dissolves like” in terms of similarity of intermolecular
forces in solvent and solute.
- discuss solid-liquid and liqid-liquid solutions and understand charge density, hydration, and explain heats of solution, solute, hydration. Understand the energetics of solvation (see equations 13.1 and 13.2 in the textbook) including
the role of entropy.
- understand the effect of temperature and pressure
on solubility of solids, liquids and gases.
- understand and apply
Henry's Law.
- define the
concentration units molality and mole fraction and interconvert
among these concentration units and molarity.
- review the terms electrolyte and non-electrolyte and define and understand colligative
properties for solutions with nonvolatile nonelectrolyte solutes. Use
Raoult's Law to determine the vapor pressure of the solution.
- use Raoult's
law to determine the vapor pressure for solutions
of volatile nonelectrolyte solutes.
- calculate vapor
pressure lowering, boiling point elevation, freezing point depression,
osmotic pressure, and molar mass for nonvolatile nonelectrolyte solutes, nonvolatile electrolyte solutes (know and use the van't Hoff factor i.)
