Hello!
The pH at the equivalence point should be pH=8,4
The reason is the following:
When a weak acid (HA) is titrated with a strong base (BOH), the neutralization reaction is the following:
HA + BOH → BA + H₂O
At the equivalence point, only BA is present, but A⁻, being the conjugate base of a weak acid, dissociates in the following way:
A⁻+H₂O⇄HA + OH⁻
The OH⁻ ions generated will make this solution to be basic, so the pH should be 8,4
Have a nice day!
