Section 17.5 - final exam

[Zellmer, Robert]

I've gotten a couple of questions about some of those difficult Ksp problems from
Section 17.5.  That section covers common-ion (CI) effect, pH effects, complex-ion
effect and amphoterism.

As for MT3, you should certainly be able to do straight Ksp problems to find the
molar solubility, the form of Ksp, concentrations of ions in solution, etc.  You should
be able to do a CI problem.  That's also in sections 17.1-17.3 in relation to acid-base
chemistry, buffers and titrations.  You are not likely to see the harder pH effects and
complex-ion problems where you have to multiply equations by a factor, add
eqns, multiply the K values and do an ICE table problem for these more complicated
Ksp questions.

For the pH effects, complex-ion effects and amphoterism just worry about those
in qualitative ways, as on MT 3.

You should understand what to do in general when an eqn is multiplied by a factor
and how that changes the value of K.  The same for what to do when you add eqns,
and how that affects K for the resulting eqn (you multiply the K values).  This was
all done in Ch 15.
