Set Up:
1. Weigh out 4.2 g of NaOH. Dissolve it quickly in about 50 mL of water in a 250-mL Erlenmeyer flask
2. Carefully transfer the solution into a 1- volumetric flask and fill the flask to the 1000 mL mark with deionized water
3. Seal the flask with its stopper, invert the flask, and shake gently. Then vent the flask.
4. Transfer the solution into a 1-L plastic bottle and close it. Label the bottle properly.
5. Start a new experiment on the data collection system
6. Connect a pH sensor and the Rotary Motion sensor to the data collection system
7. In Data Studion create a calculated dataset for volume: V = 670 * x
8. In Data Studio create a calculated dataset for the first derivative of the pH vs. Colume. Use the pH measurement for x. the equation is: dpH = derivative(2,x)
9. Display the pH on the y-axis of a graph and Volume on the x-axis
10. Setup the Titrator pump
11. Rinse the syringe on the Titrator pump
12. Setup the Titrator Accessory
13. Calibrate the pH sensor
14. Add the micro stir bar to the end of the pH sensor
15. Setup the titrant container and replace the cap on the bottle, but not airtight
16. Load the syringe on the pump with the titrant solution
17. Prime the pump on the Titrator
18. Measure about 0.200 g of KHP to the nearest milligram and record this value in Table 1. Then wash the KHP sample from the weighing dish with about 50 mL of water, into a 180-mL titration jar
19. Add enough deionized water to the solution so the tip of the pH sensor is covered with solution
20. Turn on the magnetic stirrer at a steady rate
21. Display the pH on the y-axis of a graph and Drop Count on the x-axis
