An analytical chemist is titrating 145.8 mL of a 0.7500 M solution of propionic acid (HC₂H₂CO₂) with a 1.200M solution of NaOH. The pK of propionic acid is 4.89. Calculate the pH of the acid solution after the chemist has added 103.9 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places. pH = 0 X
