Question
An analytical chemist is titrating 239.3 mL of a 0.8400M solution of methylamine (CH, NH,) with a 0.3300M solution of HNO,. The p K, of
methylamine is 3.36. Calculate the pH of the base solution after the chemist has added 257.2 mL of the HNO, solution to it.
Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO, solution added.
Round your answer to 2 decimal places.
