Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 101.7 mL of a 0.3500M solution of piperidine (C5H10NH) with a 0.05700M solution of HClO4. The pK of piperidine is 2.89.
Calculate the pH of the base solution after the chemist has added 682.9 mL of the HClO solution to it.
4
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HClO solution added.
