A chemist titrates 50.0 mL of a 0.1333 M benzoic acid (HCH,CO2) solution with 0.2560M NaOH solution at 25 °C. Calculate the pH at equivalence. The
PK, of benzoic acid is 4.20.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of NaOH solution added.
