Extracted text: An analytical chemist is titrating 239.7 mL of a 0.6100M solution of benzoic acid (HC,H,CO, with a 0.4400M solution of NaOH. The p K, of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 135.5 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 = U
