Using an acetic acid\sodium acetate buffer solution, ratio of acid to conjugate base that will be needed to maintain the pH at 5.00 is 1:1.

How do you prepare a buffer solution with a pH of 5?

  • Firstly, prepare 800 mL of distilled water in a suitable container.
  • Then add 7.721 g of Sodium acetate to the solution.
  • Next, add 352.5 mg of acetic acid to the solution.
  • Now, adjust the formed solution to final desired pH using HCl or NaOH.
  • In the end, add distilled water until the volume is 1 L.

For having, effective buffer, the number of moles of the weak acid and its conjugate base must be large as compared to the number of moles of strong acid /base that is added. The best buffering occur when the ratio of [HA] to [A-] is 1:1.
