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 55.0 mL of 0.1000 M aniline hydrochloride is titrated with 0.195 M NaOH. The Ka for anilinium ion is 2.400 × 10−5.
What pH of the solution before the titration begins?
What is the pH at the equivalence point?
What is the pH at the half-way point of the titration?
