<p><font face="serif">On Wednesday you will be doing the first of
two titration labs. These labs are different from prior labs in
the following way.</font></p>
<p><font face="serif">1. They will be conducted individually (each
person gets their own buret)<br>
</font></p>
<p><font face="serif">2. There will be an accuracy component to the
grading.</font></p>
<p><font face="serif">Your work tomorrow will directly affect the
accuracy of the results next week -- so you have to make sure
you are doing things correctly. Please review the procedures
for using a <a
href="http://cla.mercer.edu/www/mu-cla/chemistry/general-lab/upload/Using-a-buret.pdf">buret</a>.
All of your buret readings to be to the hundredth of a ml
(0.01). Remember that in this experiment the BASE goes in the
buret and you will titrating the acid in the erlenmeyer flask.
Remember -- only use the NaOH that you prepared. You NaOH and
your partners NaOH will have different concentrations and you
have to use the same one each time to have any chance of getting
accurate results.<br>
</font></p>
<p><font face="serif">Every student should do SIX titrations in lab
tomorrow. One titration will be done quickly to establish
roughly how much sodium hydroxide is required to neutralize the
acid and then you will do FIVE good titrations. This sounds like
a lot, but well prepared students have finished this lab in
under 90 minutes. <br>
</font></p>
<p><font face="serif">Please prepare your lab notebooks so that you
have places to record data for six titrations. <br>
