An analytical chemist is titrating 167.6 mL of a 0.09400 M solution of ethylamine (C₂H5NH₂) with a 0.1200 M solution of HNO3. The PK, of ethylamine is 3.19. Calculate the pH of the base solution after the chemist has added 154.8 mL of the HNO3 solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added.
