Coverage in lecture last week (Ch 17) and this coming week (Ch 17 and 19)

[Zellmer, Robert]

We got through section 17.3 (titrations) last week.  That was kind
of the "end" of acid-base chemistry (but you will use some of this
knowledge in the rest of the chapter and later in future chapters).

Understanding acids, bases, buffers and acid-base titrations is important,
not just for our class but organic chemistry and biology related classes.
This is why I spent essentially the last couple of lectures on sections 17.1
(common ion equilibria), 17.2 (buffers) & 17.3 (titrations).

Titrations pretty much combine much of what we covered in chapter 16
and sections 17.1-17.2 in one problem.   Up through 17.1 will be on
quiz 3 on Tuesday.

We also finished 17.4 (solubility equilibria) and into section 17.5 (effect
of common-ion on solubility) this past Friday.  This coming Wed. we'll
finish 17.5 and 17.6.  We skip 17.7.

I'm hoping to start Ch 19.  Skim through 19.2 before Wed..  If you look at
my ch 19 notes the first few pages are a review of some things from ch 5.
You really need to review ch 5 before we start ch 19.  We'll be doing some
things in ch 19 which are similar to some things you did in ch 5. Look at the
first 17 pages of the notes which review ch 5 material.  If you have trouble
understanding what's there you may have to review the ch 5 material in the
book.  I won't be covering these pages in lecture.  You actually have already
used some of this back in Ch 13 when we covered the energetics of solution
formation.
