<tt>Quiz 5: Chapter 17 (17.4-17.7), Ch 5 (review) and Ch 19
(19.1-19.5)
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt><b>Sections 17.4-17.6:</b>
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Solubility equilibria, solubility and molar solubility,
</tt><tt><br>
</tt><tt>solubility-product constant (Ksp), calc. Ksp from
solubility,
</tt><tt><br>
</tt><tt>calc. solubility from Ksp. Factors affecting solubility
</tt><tt><br>
</tt><tt>(common-ion effect, pH, complex-ion formation,
amphoterism),
</tt><tt><br>
</tt><tt>precipitation and separation of ions.
</tt><tt><br>

</tt><tt><br>
</tt><b><tt>Section 17.7:
</tt></b><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>We didn't go over this in any detail. You should read it
and
</tt><tt><br>
</tt><tt>understand this "Qual Scheme" and flow chart is about using
the
</tt><tt><br>
</tt><tt>knowledge learned about precipitation and Ksp from the
preceeding
</tt><tt><br>
</tt><tt>sections. You should be able to do the Sample Integrative
Exercise
</tt><tt><br>
</tt><tt>in this section. There are a couple of homework problems
over this.<br>
There are no questions on the quiz pertaining to this section.</tt><tt><br>

<tt><b>For the on-line homework:<br>
<br>
</b>Do ch 17 (17.4-17.7) tutorial set and homework review problem
set.<br>
The due dates were pointed out in a previous e-mail. Remember
there<br>
are also the DSM questions. Also, there are the practice exercise
#1<br>
problems for Ch 17 (which are not for credit).</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>On the quiz, if you need to use an ICE table, you must show
the work
</tt><tt><br>
</tt><tt>and the ICE table. When making any assumptions you should
show that
</tt><tt><br>
</tt><tt>your assumptions are okay (less than 5% error). If the
percent error
</tt><tt><br>
</tt><tt>is greater than 5%, you need to solve the resulting
quadratic equation
</tt><tt><br>
</tt><tt>or use the method of successive approximations (both shown
in class
</tt><tt><br>
</tt><tt>and in the notes). You must show this work. If you don't,
you will
</tt><tt><br>
</tt><tt>not get full credit.

</tt><tt><br>
</tt><b><tt>Chapter 5 (review material):
</tt></b><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand first law of thermodynamics (conservation of
energy and
</tt><tt><br>
</tt><tt>E=q+w from ch 5), state functions, Hess's Law, Enthalpy of
</tt><tt><br>
</tt><tt>Formation and how to use these to obtain enthalpies of
reaction.
</tt><tt><br>
</tt><tt>These things are related to what is being done in chapter
19.
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>See my chapter 19 notes (pages 1-17 to get an idea of what
sorts of
</tt><tt><br>
</tt><tt>things you need to review from chapter 5).
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><b><tt>Sections 19.1-19.5:
</tt></b><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand first law of thermodynamics (conservation of
energy and
</tt><tt><br>
</tt><tt>E=q+w from ch 5) and the 2nd and 3rd laws which deal with
entropy.
</tt><tt><br>
</tt><tt>Should be able to calc. entropy changes for both system and
</tt><tt><br>
</tt><tt>surroundings for reversible (equilibrium) and irreversible
processes.
</tt><tt><br>
</tt><tt>Understand the diff. between reversible and irreversible
processes.
</tt><tt><br>
</tt><tt>Understand the molecular interpretation of entropy and
microstates as well
</tt><tt><br>
</tt><tt>as Boltzmann's eqn (19.5). Be able to make qualitative
predictions about
</tt><tt><br>
</tt><tt>changes in entropy. Be able to calc. entropy changes using
standard
</tt><tt><br>
</tt><tt>entropies (eqn 19.8).
</tt><tt><br>
</tt><tt>
</tt><tt><br>
</tt><tt>Understand free energy and how it relates to enthalpy,
entropy, temp.
</tt><tt><br>
</tt><tt>and spontaneity. Know how to use std. free energies of
formation to
</tt><tt><br>
</tt><tt>calc. std. free energy changes for a rxn (eqn 19.14).
