Why is the equivalence point of a weak acid-strong base titration above 7.0? How can the data reflect this?

The titration of a weak acid with a srong base produces a salt of the two. The anion is hydrolyzed in water solution but the cation is not.
A^- + HOH ==> HA + OH^-
The production of OH^- shows that a water solution of this salt will be basic. The data will reflect that because you probably used an indicator that changed color above 7.0.
