If a buffer solution is 0.230 M0.230 M in a weak base (?b=7.4×10−5)Kb=7.4×10−5) and 0.540 M0.540 M in its conjugate acid, what is the pH?
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 0.460 M in both propanoic acid (C,H,COOH) and its conjugate base (C,H,CO0-). Calculate the maximum volume of 0.380 M HCl that can be added to the buffer before its buffering capacity is lost.
