Experiment Title
Indication of pH and Buffer Solutions Statement of Purpose Train the preparation of the acetate buffer solution (pH = 4.8) and other solutions. Practice the pH measurements. Test the buffer capacity of the prepared buffer solution.
Hypothesis to test:
- property of buffer solution to keep pH, when the strong acid or base are added; - red cabbage juice acts as a natural indicator, which helps to identify the pH of the solution.
Description of the Experiment
Acetate Buffer Preparation: mix 10 ml of 0.2 M acetic acid with 15 ml of 0.2 M sodium acetate, add 75 ml of distilled water was added. Store in an ...
