Section 17.7, metal sulfides

[robert zellmer]

We did not cover Section 17.7 (qualitative analysis and the flow chart)
in class.  You should read this section and do the 2-3 questions covering
it (17.77, 17.79-17.80) since it will help with some of the things 
you've seen
in sections 17.4-17.6 and in lecture.  You should be able to do the sample
integrative exercise at the end of this section.

Also, for the metal sulfides I did not do any quantitative calculations
in class.  We skipped that part.  I did go over the form of the equilibrium
eqn for metal sulfides which corresponds to the Ksp for metal sulfides.
This same equil. eqn. is shown in a footnote in Table D.3 in Appendix D of
the textbook.  You need to know this eqn for a couple of questions in the
homework.
