An analytical chemist is titrating 89.4 mL of a 0.9900M solution of benzoic acid (HC H,CO₂) with a 0.9200M solution of NaOH. The pk of benzoic acid is 4.20. Calculate the pH of the acid solution after the chemist has added 77.1 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.
