WebSecond, you will make 100 mL of a buffer also with pH = 5, but with a higher buffering capacity, using 5 mL of a 0.5 M acetic acid solution. Although a buffer will resist a change in pH, eventually enough acid or base can be added to destroy it. The amount of acid or base needed to change the pH of a buffer is known as the "buffering capacity."
