I have a help file for exp 19 post-lab calc.,<br>
<br>

<b>Exp 19 - Help for Exp 19</b> </a><br>
<br>
<br>
Exp 19 doesn't list which sample calcs you need for exp 19 in the
manual.<br>
You always need to show sample calcs. It does state w/o detail what
<br>
to do on page 139. They are on the rubric.<br>
<br>
Here's what to do: <br>
<br>
Part A: <br>
<br>
Dilution calc. for SbCl3 <br>
Dilution calc. for H+ and Cl- , last step (after adding 2 mL of 6.0
M HCl) - lower<br>
right box<br>
<br>
Part B: <br>
<br>
Lines 3-5 (Molarities of SbCl3, H+/Cl- and K, the equil. constant) <br>
<br>
Part C: <br>
<br>
Table 1: Molarity of Cl- (just show it for one row after adding
12.0 M HCl). <br>
Table 2: Molarity of Cl- after adding water to the solution from
table 1. <br>
Last part: This involves the ethanolic soln of Co<sup
class="moz-txt-sup"><span
style="display:inline-block;width:0;height:0;overflow:hidden">^</span></sup>^2+.
Show calculation of <br>
Cl- in the blue soln (last line). This means you
have to covert the <br>
drops added to volume (mL). The conversion is given
on page 136. <br>
<br>
Answer the questions on the report sheets. <br>

Don't forget the post-lab on Carmen. <br>
