Acetic acid, HOAc, has a Ka = 1.73x10^-5. You need to prepare a buffer solution with a pH of 5.00 from a solution of 1M acetic acid (HOAc) and 1 M sodium acetate (NaOAc). How many mL of NaOAc should be added to the 30mL of HOAc solution to create the buffer? Using this buffer as an example, provide the reactions that allow the buffer to resist changes in pH upon addition of 1) NaOH and 2) HCl.

Why will a buffer yield when equal volumes of 0.20M NH3 and 0.10M HCl are mixed?
Explain why equal volumes of 0.1M CH3COOH and 0.1M CH3CO2- function as a buffer solution, but equal volumes of 0.1M HCl and 0.1M NaCl or equal volumes of 0.1M HCl and 0.1M NaOH do not.
