A chemist titrates 140.0 mL of a 0.7683 M propionic acid (HC₂H₂CO₂) solution with 0.2764 MKOH 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. pH = 0 X 5
