Question

An analytical chemist is titrating 246.1 mL of a 0.8100 M solution of methylamine (CH3NH₂) with a 0.4000 M solution of HNO3. The p K, of methylamine is 3.36. Calculate the pH of the base solution after the chemist has added 370.0 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.
