Consider two 1 liter solutions: solution A contains a strong base at 0.1 M, solution B contains a weak base at 0.1 M with Kb = 105. To both solutions, you add 0.05 mol of a strong acid. Select all statements that correctly describe the resulting solutions: The pH of solution B is 9.0. The pH of solution A is 12.7. Solution A is still a strong base, solution B is a buffer. More acid needs to be added for both solutions to reach the equivalence point. Solution A is now a weak base, solution B is weakly acidic. Solution A has not reached the equivalence point, solution B is past the equivalence point. Both solutions are now buffers.

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 0.240 M in both hydrofluoric acid (HF) and its conjugate base (F). Calculate the maximum volume of 0.110 M HCI that can be added to the buffer before its buffering capacity is lost.
