An analytical chemist is titrating 156.4 mL of a 0.3600 M solution of formic acid (H,CO,) with a 0.6800 M solution of NaOH. The pK of formic acid is 3.74. Calculate the pH of the acid solution after the chemist has added 91.45 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.
