Question
An analytical chemist is titrating 122.4 mL of a 0.2000M solution of propylamine (C,H,NH,) with a 0.07300M solution of
HNO2. The p K, of propylamine is 3.46. Calculate the pH of the base solution after the chemist has added 122.3 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.
Round your answer to 2 decimal places.
