<tt>Quiz 5 will cover the following: </tt><tt><b>Chapter 16
(16.1-16.8)</b></tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> </tt><tt><b>Sections 16.1-16.5:</b></tt><tt><b><br>
</b></tt><tt><br>
</tt><tt> Acids and bases (Arrhenius and Bronsted-Lowry theory),</tt><tt><br>
</tt><tt> conjugate acid/base pairs, autoionization of water, K</tt><tt><sub>w</sub></tt><tt>,
pH, pOH,</tt><tt><br>
</tt><tt> strong acids ands bases and weak acids and bases. You
MUST</tt><tt><br>
</tt><tt> know the 7 common strong acids and the strong bases (those</tt><tt><br>
</tt><tt> discussed in the book, notes, class and on the class web
page).</tt><tt><br>
</tt><tt> All other acids or bases you see will be weak acids or
bases</tt><tt><br>
</tt><tt> (unless told otherwise). You need to be able to do
calculations</tt><tt><br>
</tt><tt> for strong acids and bases.</tt><tt><br>
</tt><tt> </tt><tt><br>
</tt><tt> </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.</tt><tt><br>
</tt><tt><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>
</b></tt><tt><b>the "Helpful Tidbits" link and you will find them
