An analytical chemist is titrating 195.5mL of a 0.1800M solution of dimethylamine CH32NH with a 0.4000M solution of HNO3 . The pKb of dimethylamine is 3.27 . Calculate the pH of the base solution after the chemist has added 12.5mL 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.
