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.
Sodium acetate buffers are used for purification and precipitation of
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.
