Chemistry titration problem 3?
Aniline hydrochloride, [C6H5NH3]Cl, is a weak acid. [Its conjugate base is the weak base aniline, C6H5NH2 . The acid can be titrated with a strong base such as NaOH:
Assume 48.2 mL of 0.100 M aniline hydrochloride is titrated with 0.185 M NaOH. (Ka for aniline hydrochloride is 2.4 multiplied by 10-5.)
Calculate the pH of the solution after adding 5.0, 10.0, 20.0, and 30.0 mL of the base.
