Sodium acetate buffers are used for purification and precipitation of nucleic acids, as well as for protein crystallization and staining gels used in protein electrophoresis. It is very popular in hematology, since there is some evidence that acetate-buffered infusions show improved stability. Acetate buffers are inexpensive and simple to prepare, and can be stored at room temperature. 27-29. Calculate the pH of the acetate buffer solution that contains 0.50M acetic acid (Kb=5.56x10-10) and 0.50M sodium acetate. 30-32. Calculate the change in pH that occurs when 0.010 mol NaOH(s) is added to 1.0L of the acetate buffer. 33-35. Compare the pH change with that when 0.010M of NaOH is added to 1.0L of pure water. 36-40. How can the pH of the buffered solution not increase even though a strong base, NaOH, is added? Explain using the ions present.
