An analytical chemist is titrating 195.2mL of a 0.8100M solution of benzoic acid HC6H5CO2 with a 0.7200M solution of NaOH. The pKa of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 87.44mL 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. An analytical chemist...
