An analytical chemist is titrating 164.9 mL of a 0.3400M solution of propylamine (C,H,NH,) with a o.3700M solution of HNO,. The pK, of propylamine is 3.46. Calculate the pH of the base solution after the chemist has added 67.7 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
