8. Titrate the solution by adding silver nitrate, one drop at a time,
swirling after each addition. Add drops until a red color persists in
the flask.
9. When the red color persists, record the final volume of silver nitrate
in the burette on the data table. Subtract the two volumes (final −
initial) to determine the milliliters of silver nitrate used.
10. Discard the sample, rinse the flask, and repeat the same titration
again with another 10 ml of sample 1 so that you have two titrations
with the same solution. Record all data on the data table.
11. Repeat steps 4 through 9 with samples 2 and 3.
12. Answer Analysis questions 2 through 7.
