Suppose that you were asked to prepare 1.00L of a pH 5.00 CH₃CO₂Na/CH₃CO₂H buffer that must be able to resist the addition of 100.0mL of 0.200M NaOH without exceeding a pH of 5.20. The buffer must be of the lowest possible concentration. You have 1.00M acetic acid (CH₃CO₂H, pK_a=4.76), 1.00M NaOH, and deionized water at your disposal. How would you prepare the buffer? Show all work.
