An impure sample of benzoic acid (HC7H5O2) is titrated with 0.1278M NaOH. A 0.5038 gram sample requires 23.81mL of sodium hydroxide to reach the endpoint. What is the percent by mass of benzoic acid in the sample?

HC7H5O2(aq) + NaOH(aq) = NaC7H5O2 + H2O (l)

Calculate the pH at the halfway point and at the equivalence point for each of the following titrations.

a. 100.0 mL of 0.10 M HC₇H₅O₂ (K_a = 6.4 × 10^–5) titrated by 0.10 M NaOH

b. 100.0 mL of 0.10 M C₂H₅NH₂ (K_b = 5.6 × 10^–4) titrated by 0.20 M HNO₃

c. 100.0 mL of 0.50 M HCl titrated by 0.25 M NaOH
