Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 241.7 mL of a 0.4900M solution of methylamine (CH3NH2) with a 0.7800M solution of HNO3. The pK of methylamine is
3.36. Calculate the pH of the base solution after the chemist has added 17.7 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.
