✓ 1 2 3 pH = 0 4 X 5 6 ? 7 8 An analytical chemist is titrating 234.1 mL of a 0.4900M solution of aniline (CH²NH₂) with a 0.4800M solution of HNO3. The pK, of aniline is 9.37. Calculate the pH of the base solution after the chemist has added 269.8 mL of the HNO3 solution to it. 9 Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added. Round your answer to 2 decimal places. ✓ 10
