Quiz 5 material

[robert zellmer]

Quiz 5 will cover the following: *Chapter 16 (16.1-16.7)*

*Sections 16.1-16.5:**
*
Acids and bases (Arrhenius and Bronsted-Lowry theory),
conjugate acid/base pairs, autoionization of water, K_w , pH, pOH,
strong acids ands bases and weak acids and bases.  You MUST
know the 7 common strong acids and the strong bases (those
discussed in the book, notes, 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.

*Sections 16.6-16.7:*

You need to be able to do calculations for weak acids and bases
(using ICE tables).  You should understand what polyprotic acids
are and how to do calculations for them.

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.  Simply showing the ratio of K_a /[HA]_o < 10^-3
is not sufficient (similarly for a base using K_b and [base]_o ).

*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.*
