An analytical chemist is titrating 163.7 mL of a 0.7200M solution of benzoic acid (HC,H,CO,) with a 0.7000M solution of NaOH. The p K of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 121.7 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. dlo
