This Lab can be accessed from Dr. Belford's homepage:

Open: **Sixth Lab: Solubility Product
Lab**

Your report needs to include:

1. This sheet of paper as cover page or an appropriate cover page

2. Unknown Number on cover sheet

3. Value of K at room temperature. Show math

4. Value of DG^{0}
at room temperature (show math)

5. Value of K and DG^{0}
at 95^{o}C .
You can change the temperature by right clicking on the flask and
choosing the thermal properties setting.
You must specify the temperature and show the math.

6. Value of DS^{0}
, show math.

7. Value of DH^{0}
, show math.

**Note: You do not use pH to
calculate ion concentration**s. They are given by the virtual lab. Also, you can determine the formula of the
salt from the charge of the ion. If the
salt had a cation of +2 (C^{+2}) and an anion
of -1 (A^{-} ), then the formula is CA_{2}
and the anion concentration if twice that of the cation
as

CA_{2} -->
C^{+2} + 2A^{-}

Furthermore,
for the above salt, the concentration of the anion would be twice that of the
cation.
