Problem
During the titration of a monoprotic weak acid with a strong base, which statement correctly describes the pH after exactly one-half of the volume required to reach the equivalence point has been added?
(a) It is always 7.00, independent of the acid’s strength.
(b) It is numerically equal to the conjugate base’s pKb.
(c) It is numerically equal to the acid’s pKa.
(d) It cannot be predicted without knowing the initial acid concentration.
