A chemist titrates 250.0 mL of 0.5849 M aniline C6H5NH2 solution with 0.4070 M HNO3 solution at 25 °C Calculate the pH at equivalence. The pKb of aniline is 4.87

Round your answer to 2 decimal places.

Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HNO3

Note for advanced students: you may assume the total volume of the solution equals to the initial plus the volume of HNO3 solution added.

Calculating the exact pH is, as usual in titration problems, a solution stoichiometry (moles/molarity/volume) problem followed by an equilibrium composition problem.

First, you need to calculate the molarity of C6H5NH2 after the titration reaction has run. This is the stoichiometry problem.
Then you can set up a reaction table and use the K
a equation for C6H5NH2 to calculate the equilibrium molarity of HNO3This is the equilibrium problem
