Calculate the pH of the base solution after the chemist has added 71.3 mL of the HNO, solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO, solution added.

An analytical chemist is titrating 186.4 ml of a 0.7700M solution of anilline (C,H₂NH₂) with a 0.7300M solution of HNO,. The pK, of aniline is 9.37. Calculate the pH of the base solution after the chemist has added 51.8 mL of the HNO, solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO, solution added. Round your answer to 2 decimal places. pH = 0 X 2
