An analytical chemist is titrating 163.6 mL of a 0.7600M solution of diethylamine ((C₂H₂)2NH) with a 0.5800M solution of HNO3. The pK, of diethylamine is 2.89. Calculate the pH of the base solution after the chemist has added 238.5 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. Round your answer to 2 decimal places.
