Question

An analytical chemist is titrating 68.9 mL of a 0.2300 M solution of isopropylamine ((CH₂)₂CHNH₂) with a 0.3700 M solution of HNO 3. The P K of isopropylamine is 3.33. Calculate the pH of the base solution after the chemist has added 19.0 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.
