Problem
A buffer solution is prepared by dissolving a monoprotic acid HA and its sodium salt NaA to make 250.0 mL of solution in which [HA]=0.250M and [A−]=0.250M (pKa=7.20). What maximum volume of 0.100 M NaOH can be added before the pH of the buffer reaches 7.40? Assume volumes are additive and report the volume in milliliters to three significant figures.
