What is the main property of a buffer solution? A buffer does not allow any change in pH. A buffer resists drastic changes in pH upon addition of acid or base. Buffer solutions have an unlimited capacity to resist pH change. Upon adding a small amount of a strong acid or strong base, a buffer increases the change in pH to a very large amount

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 0.280 M in both propanoic acid (C2H5COOH) and its conjugate base (C2H5COO–). Calculate the maximum volume of 0.200 M HCl that can be added to the buffer before its buffering capacity is lost.
