Question

An analytical chemist is titrating 104.7 ml. of a 0.3500 M solution of trimethylamine ((CH₂), N) with a 0.3400 M solution of HNO3. The pK, of trimethylamine is 4.19. Calculate the pH of the base solution after the chemist has added 127.3 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 HNO3 solution added.
Round your answer to 2 decimal places.
