a = 6.7) to buffer a solution at pH 4, or to use acetic acid (pK a = 4.7) to buffer near neutral pH. What Are the Criteria to Consider When Selecting a Buffer? Target pH Of primary concern is the target pH of the solution. This narrows the possible choices to those buffers with pK a values within 1 pH unit of the target pH. pH pK CH COO CH COOH ...

Experiment 7: Preparation of a Buffer

3. Load a 50 mL buret with your Standardized NaOH solution (Experiment 6) 4. Use the pH meter to monitor the titration of the buffer until the pH changes 1 unit. Run two titrations: a quick one and a careful one. For the quick one, add NaOH in 1 mL increments. For the careful one, use your best judgment in adding titrant. 5. Repeat Steps 2-4 ...
