Procedural Steps:

1. Ground an anti-acid pill in a mortar to a fine powder substance.

2. Weighed out for each trial(3 total) approximately 1.0 grams of the powder and washed the substance into a 250 mL flask with 50 mL of deionized water.

3. Transfered by pipeting, 100 mL of the 0.1 molar HCl into the same flask.

4. Boiled the solution on a hot plate for about 5 minutes until the anti-acid pill was completely dissolved in the HCl. (the solution appeared murky)

5. Once boiled, allowed the solution to cool to room temperature.

6.  Transfered the solution into a 240 mL titration jar and washed the flask with deionized water.

7.  After setting up the data collection system,titrator and accessory pump, calibrating the pH sensor, and adding the micro stir bar to the end of the pH sensor, the titrator jar with the solution was attached to the hockey-puck set-up and the magnetic stirrer was turned on at a steady rate.

8.  Started recording data, pressed "Run" on the titrator and observed graph until the pH reached an equilibrium point and continued on past until the curve flattened out.

9.  Stopped data recording, and saved the graph data.
