An analytical chemist is titrating 173.5 mL of a 0.6900 M solution of propionic acid (HC₂H,CO₂) with a 1.200 M solution of KOH. The P K of propionic acid is 4.89. Calculate the pH of the acid solution after the chemist has added 119.5 ml. of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places.
