An analytical chemist is titrating 105.5 mL of a 0.4700 M solution of acetic acid (HCH,CO) with a 0.4400 M solution of KOH. The pKof acetic acid is 4.70. Calculate the pH of the acid solution after the chemist has added 122.6 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places. pH = 0
