Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 115 mL of a buffer that is 0.180 M in both acetic acid (CH3COOH) and its conjugate base (CH3COO–). Calculate the maximum volume of 0.100 M HCl that can be added to the buffer before its buffering capacity is lost.

Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 175 mL of a buffer that is 0.160 M in both hydrofluoric acid (HF) and its conjugate base (F–). Calculate the maximum volume of 0.390 M HCl that can be added to the buffer before its buffering capacity is lost.
