Quiz 5 will cover the following: <b>Chapter 16 (16.1-16.7)</b><br>
<br>
<b>Sections 16.1-16.5:</b><b><br>
</b><br>
Acids and bases (Arrhenius and Bronsted-Lowry theory),<br>
conjugate acid/base pairs, autoionization of water, K<sub>w</sub>,
pH, pOH,<br>
strong acids ands bases and weak acids and bases. You MUST<br>
know the 7 common strong acids and the strong bases (those<br>
discussed in the book, notes, class and on the class web page).<br>
All other acids or bases you see will be weak acids or bases<br>
(unless told otherwise). You need to be able to do calculations<br>
for strong acids and bases.<br>
<br>
<b>Sections 16.6-16.7:</b><br>
<br>
You need to be able to do calculations for weak acids and bases<br>
(using ICE tables). You should understand what polyprotic acids<br>
are and how to do calculations for them.<br>
<br>
On the quiz, if you need to use an ICE table, you must show the work<br>
and the ICE table. When making any assumptions you should show that<br>
your assumptions are okay (less than 5% error). If the percent
error<br>
is greater than 5%, you need to solve the resulting quadratic
equation<br>
or use the method of successive approximations (both shown in class<br>
and in the notes). You must show this work. If you don't, you will<br>
not get full credit. Simply showing the ratio of K<sub>a</sub>/[HA]<sub>o</sub>
< 10<sup>-3</sup> <br>
is not sufficient (similarly for a base using K<sub>b</sub> and
[base]<sub>o</sub>).<br>
<br>
<b>There are 5 links concerning acids and bases on my class web
page. Go to</b><b><br>
</b><b>the "Helpful Tidbits" link and you will find them at the
bottom. These</b><b><br>
</b><b>came about from answering e-mail questions from students over
the years.</b><b><br>
</b><b>The first two links apply to the material covered by this
quiz.</b><br>
