Overview:
Learn About Solids, Phase Diagrams,
Colligative Properties and More
This module has two portions. The first portion
(covered in Chapter Eleven) extends our discovery of intermolecular
forces from module four and expands to reach solids and phase
diagrams. The second portion (Chapter 13) examines solutions and their special properties (collectively referred to as colligative
properties).
Chapter 11 continues our discussion intermolecular
forces. We will now look at the intermolecular forces
of solids, learning about simple
cubic solids (simple cubic, body
centered cubic and face centered
cubic systems) and how to determine their radius and density using
relatively simple transformations. We will also explore phase
diagrams and understand how to use them. We will see
once again how ordinary water is
quite special with regards to other solvents, mainly due to hydrogen
bonding.
For a complete list of important concepts in
Chapter 11, see the Chapter 11 Study Guide.
Chapter 13 explores the behaviors of solutions,
and remember that a solution has both a solute and
a solvent. The first part of Chapter 13 introduces new concentration definitions,
including molality, weight
percent and mole fraction.
We will use these definitions when discussing the colligative
properties - a series of behaviors exhibited by solutions.
We will explore Henry's Law (gases
in a solvent), Raoult's Law (vapor
pressure depression), boiling point
elevation, freezing point elevation,
and osmosis. Finally, we shall briefly
explore the Tyndall Effect which
occurs from colloids and suspension,
special forms of "solutions" where the solute particle
size is quite large.
