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 145 mL of a buffer that is 0.100 M in both propanoic acid (C2H;COOH) and its conjugate base (C2H5CO0). Calculate the maximum volume of 0.420 M HCl that can be added to the buffer before its buffering capacity is lost. mL
