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 195 mL of a buffer that is 0.500 M in both hydrofluoric acid (HF) and its conjugate base (F−). Calculate the maximum volume of 0.190 M HCl that can be added to the buffer before its buffering capacity is los
