I was just wondering how I would determine the pKb of a weak base that was titrated with a strong acid on a titration curve at the EQUIVALENCE POINT. And from this, how would I find the pH? PLEASE HELP!!

I took 25 mL of an unknown weak acid and added it to 10 mL of NaOH solution. I measured the pH and got 2.88 with concentration of NaOH @ .0098 and weak acid at 0.0102. What is pKa for the acid?
