Provide a net ionic equation to show  why a given weak/strong titration is not 7 at the equivalence point

Let us say weak acid is HA  and strong base is MOH
Strong base is fully dissociated
HA + OH^- ----> H2O + A ^-
At the equivalence point [HA] and [OH^-]= 0.0M
So it means pH is controlled by A- and H2O
Now A^- is a stronger conjugate base of a weak acid and will react with water to generate OH^- is the solution which make the pH more than 7
A^-  + H₂O <---> HA + OH ^-
