Aniline hydrochloride, [C6H5NH3]Cl, is a weak acid. Its conjugate base is the weak base aniline, C6H5NH2. Ka = 2.40 X 10^-5. Required:
1. Calculate pH at points if 50 mL of 0.100 aniline hydrochloride is titrated with 0.185 M NaOH.
2. Calculate the pH (a)before titration begins (b)at E. P (c) at the midpoint (d) after 20 mL of NaOH (e) after 30 mL of NaOH
