Quiz 3:  Chapter 16 (16.1-16.9)

Acids and bases (Arrhenius and Bronsted-Lowry theory),
conjugate acid/base pairs, autoionization of water, Kw, pH, pOH,
strong acids ands bases and weak acids and bases.  You need to
understand how to set up an equilibrium (ICE) table.  You also
need to know the common strong acids and strong bases (those
discussed in the book, class and on the class web page).  All
other acids or bases you see will be weak acids or bases (unless
told otherwise).  You need to be able to do calculations for
strong acids and bases and for weak acids and bases (ICE tables).
You should understand what polyprotic acids are and how to do 
calculations for them.

Relationship between Ka, Kb and Kw for a conjugate acid-base pair.

You need to understand hydrolysis problems (acid-base properties of
salt solutions).  Know how the relationship between Ka, Kb and Kw
for a conjugate acid-base pair is used for these problems.  Be able
to do calculations for salt solutions to determine pH, etc.  This means
setting up an equilibrium (ICE) table.  You need to understand what the
controlling equilibrium reaction is in order to set up the proper ICE table.

On the quiz, if you need to use an ICE table, you must show the work
and the ICE table.  When making any assumptions you should show that
your assumptions are okay (less than 5% error).  If the percent error
is greater than 5%, you need to solve the resulting quadratic equation
or use the method of successive approximations (both shown in class
and in the notes).  You must show this work.  If you don't, you will
not get full credit.

You should be able do to homework problems 16.1(a), 16.2-16.8, 16.11-16.86,
16.101, 16.102(c,d,e), 16.103-16.113, 16.115-16.118, 16.120, 16.122-16.124.

For those of you using the 11th edition the quiz covers sections 16.1-16.9
and homework problems 16.1(a), 16.2-16.8, 16.13-16.90, 16.105, 16.106(c,d,e),
16.107-16.119, 16.121-16.124, 16.126-16.130.

For those of you using the 10th edition the quiz covers sections 16.1-16.9
and homework problems 16.1(a), 16.2-16.7, 16.11-16.78, 16.105, 16.106(c,d,e),
16.107-16.115, 16.117-16.120, 16.122-16.126.


There are 5 links concerning acids and bases on my class web page.  Go to
the "Helpful Tidbits" link and you will find them at the bottom.  These
came about from answering e-mail questions from students over the years.
The first two links apply to the material covered by this quiz.
