A chemist titrates 70.0 mL of a 0.4298 M propionic acid (HC,H,CO,) solution with 0.2267 M KOH solution at 25 °C. Calculate the pH at equivalence. The pK, of propionic acid is 4.89. 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 KOH solution added.
