An analytical chemist is titrating 86.9 mL of a 0.6900M solution of ethylamine (C2H5NH2) with a 0.4900M solution of HNO 3. The pK, of ethylamine is 3.19. Calculate the pH of the base solution after the chemist has added 138.2 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.
