A chemist titrates 180.0 mL of a 0.5163 M acetic acid (HCH, CO₂) solution with 0.7728 M NaOH solution at 25 °C. Calculate the pH at equivalence. The PK of acetic acid is 4.76. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of NaOH solution added.
