<big><font size="2"><big>We did not cover Section 17.7 (qualitative
analysis and the flow chart)<br>
in class. You should read this section and do the 2-3
questions covering<br>
it (17.77, 17.79-17.80) since it will help with some of the
things you've seen<br>
in sections 17.4-17.6 and in lecture. You should be able to
do the sample<br>
integrative exercise at the end of this section.<br>
<br>
Also, for the metal sulfides I did not do any quantitative
calculations<br>
in class. We skipped that part. I did go over the form of
the equilibrium<br>
eqn for metal sulfides which corresponds to the Ksp for metal
sulfides.<br>
This same equil. eqn. is shown in a footnote in Table D.3 in
Appendix D of<br>
the textbook. You need to know this eqn for a couple of
questions in the<br>
homework.<br>
