Problem 116
Two acids, each approximately 0.01 M in concentration, are titrated separately with a strong base. The acids show the following pH values at the equivalence point: \(\mathrm{HA}, \mathrm{pH}=9.5,\) and \(\mathrm{HB}\) \(\mathrm{pH}=8.5\) (a) Which is the stronger acid, HA or HB? (b) Which of the conjugate bases, \(A^{-}\) or \(B^{-},\) is the stronger base?
