Acids vs. Bases

A fairly quick overview of the procedure:

1. Use a pipet bulb to pipet 10mL of HCL solution into a 250mL beaker. Add 50mL of distilled water.
2. Place the beaker on a magnetic stirrer and add a stirring bar.
3. Use a utility clamp to suspend a pH Sensor on a ring stand. Position the pH Sensor in the HCL    Solution and adjust its position so that it is not in the way of the stirring bar.
4. Obtain a 50mL buret and use a utility clamp to attach the buret to the rin stand. Fill the buret with 10mL of NaOH Solution.
5. Prepare the computer for data collection in LoggerPro.
6. Before adding NaOH titrant, click the collect button and moniot the pH for about 5 seconds. Once the pH reading has stabilized, click the keep button. In the edit box, type "0."
7. Begin the titration process and enter the values as you go.
8. Clean Up!

Here is our lovely graph!
