An analytical chemist is titrating 206.4 mL of a 0.5200 M solution of propionic acid (HC,H,CO,) with a 1.100 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 107.9 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.
