<tt>Quiz 5 will cover the following: </tt><tt><b>Chapter 16
(16.6-16.10)</b></tt><tt><br>
</tt><br>
<tt><tt><b>Sections 16.6-16.7:</b></tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> You need to be able to do calculations for weak acids
and bases</tt><tt><br>
</tt><tt> (using ICE tables). You should understand what
polyprotic acids</tt><tt><br>
</tt><tt> are and how to do calculations for them.</tt><tt><br>
</tt><tt><br>
</tt><tt><b>Section 16.8:<br>
<br>
</b></tt><tt> Relationship between K</tt><tt><sub>a</sub></tt><tt>,
K</tt><tt><sub>b</sub></tt><tt> and K</tt><tt><sub>w,</sub></tt><tt>
pK</tt><tt><sub>a</sub></tt><tt>, pK</tt><tt><sub>b</sub></tt><tt>
and pK</tt><tt><sub>w</sub></tt><tt> for a</tt><tt><br>
</tt><tt>conjugate acid-base pair.<br>
<br>
</tt></tt><tt><tt><tt><tt><b>Section 16.9:<br>
</b><br>
You need to understand hydrolysis problems (acid-base
properties of<br>
salt solutions). Know how the relationship between </tt></tt></tt></tt><tt><tt><tt><tt><tt><tt>K</tt><tt><sub>a</sub></tt></tt></tt></tt></tt></tt><tt><tt><tt><tt><tt><tt>,
K</tt><tt><sub>b</sub></tt><tt> and K</tt><tt><sub>w </sub></tt></tt>for<br>
a conjugate acid-base pair is used for these problems. Be
able to do<br>
calculations for salt solutions to determine pH, etc. This
means<br>
setting up an equilibrium (ICE) table. You need to
understand what<br>
the controlling equilibrium reaction is in order to set up
the proper<br>
ICE table.<br>
</tt></tt></tt></tt><br>
<tt><tt><tt><tt><tt><tt><tt><tt><b>Section 16.10:<br>
</b></tt></tt></tt></tt><b> </b></tt></tt></tt><tt>
</tt><tt><br>
Acid-base behavior and structure. Make comparisons of acid and
base<br>
strengths for different acids based on structure.<br>
<br>
<br>
</tt><tt> On the quiz, if you need to use an ICE table, you must
show the work</tt><tt><br>
</tt><tt> and the ICE table. When making any assumptions you
should show that</tt><tt><br>
</tt><tt> your assumptions are okay (less than 5% error). If the
percent error</tt><tt><br>
</tt><tt> is greater than 5%, you need to solve the resulting
quadratic equation</tt><tt><br>
</tt><tt> or use the method of successive approximations (both
shown in class</tt><tt><br>
</tt><tt> and in the notes). You must show this work. If you
don't, you will</tt><tt><br>
</tt><tt> not get full credit. Simply showing the ratio of K</tt><tt><sub>a</sub></tt><tt>/[HA]</tt><tt><sub>o</sub></tt><tt>
< 10</tt><tt><sup>-3</sup></tt><tt> </tt><tt><br>
</tt><tt> is not sufficient (similarly for a base using K</tt><tt><sub>b</sub></tt><tt>
and [base]</tt><tt><sub>o</sub></tt><tt>).</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> </tt><tt><b>There are 5 links concerning acids and
bases on my class web page. Go to</b></tt><tt><b><br>
