show calculations of expected chemical shifts for Hc and Ha

6. 25.00 mL of each of 0.100 M solutions of acids HA and HB, are titrated separately with a NaOH solution. In the titration of HA with NaOH, the pH at the equivalence point in 9.5. For HB, the pH at the equivalence point of the titration is 8.5. Which of the following statements is true? a) HB is a stronger acid than HA and will therefore require a larger volume of NaOH to reach the equivalence point. b) HA is a stronger acid than HB and both HA and HB require the same volume of NaOH to reach the equivalence point. c) HA is a stronger acid than HB and will therefore require a larger volume of NaOH to reach the equivalence point. d) HB is a stronger acid than HA and both HA and HB require the same volume of NaOH to reach the equivalence point. e) B is a stronger base than A because the pH at the equivalence point is lower for HB.
