Calculating the pH of a weak base titrated with a strong acid
b
An analytical chemist is titrating 116.9 mL of a 0.7700M solution of aniline (C6H5NH2) with a 0.5300M solution of HNO3. The pK of aniline is 9.37.
Calculate the pH of the base solution after the chemist has added 184.2 mL of the HNO 3 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.
