Experiment 3: Acids and Bases

Hypothesis:

My Hypothesis is that Aspirin would be the
Best buffer because it has a strong acid content and it
May be able to withstand changes better.

Materials Needed:

-CBL System
-TI Graphing Calculator
-Venire pH System
-Venire DIN adapter Cable
-250- mL beaker
-Various Biological Organisms
-Various Non Biological Organisms
-Graphical Analysis or graph paper
-.10 M HCI (ACID) with Dropper
-.10 M NaOH (Base) with Dropper
-50 mL graduated cylinder
-One rinse bottle with distilled water
-Goggles
-Lab Apron
-50- mL beaker
-Various simple biologic al Materials

Procedure:

1. Obtain and Wear goggles
2. Before each use of the pH probe you need to rinse the tip of the electrode thoroughly with distilled water.
3. Prepare the pH system for data collection -plug in pH amp -connect the CBL syste...
