|||| Titration & Lewis Question 7 of 10 (1 point) | Question Attempt: 2 of Unlimited 2 pH = ✓ 3 0 4 5 X 6 An analytical chemist is titrating 152.9 mL of a 0.8900M solution of formic acid (H₂CO₂) with a 0.9500M solution of KOH. The p K of formic acid is 3.74. Calculate the pH of the acid solution after the chemist has added 43.15 mL of the KOH solution to it. 9 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume KOH solution added. Round your answer to 2 decimal places. ✓ 10
