Titration evidence

A weak monoprotic acid is titrated with strong base. Initial pH=2.9; at half-equivalence pH=4.8; equivalence pH=8.7.

  1. At half-equivalence, pH=pKa.
  2. Equivalence above 7 fits a basic conjugate base.
  3. The data distinguish weak from strong acid.

Which conclusion is strongest?
