A solution was prepared by mixing 50 mL of 0.1 M benzoic acid with 50 mL of 0.05 M sodium benzoate. The Ka of benzoic acid is 6.3 x 10-5. Compute for the pH value of the resulting buffer.
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.
Preparation of 40 mL of an acetate buffer (pH 4.2) 0.2 M acetic acid (pKa = 4.8) and 0.2 M sodium acetate solutions are provided. Q show the calculation the volumes of the two solutions (acetic acid and sodium acetate) should be mixed for the preparation of the acetic buffer with pH 4.2 by the Henderson-Hasselbalch equation.
Unlike propanoic acid, magnesium hydroxide, Mg(OH)2 does not dissolve well in water. The Ksp of Mg(OH)2 is only about 2 × 10–11. Yet, what will be the result if 75 mL of 0.0050 M Mg2+ are mixed together with 55 mL of 0.00010 M OH–? Write an appropriate expression (equation) for the Ksp of Mg(OH)2(s). Then, calculate Qsp and state accordingly whether a precipitate will form or not
Many chemical reactions are carried out in the presence of buffers. Use the Henderson-Hasselbalch equation to provide a recommendation for a suitable acete/acetic acid buffer under the following reaction conditions. a) If a checial reaction produces hydroxide ion, OH-, what would be the range for the target pH of a buffer soution that would favor pH stabilizatoin under these conditions? Explain.
