PROBLEM 4: In the titration of 100 ml of weak acid, 27.63ml of 0.09381M of NAOH was needed to reach the equivalence point. Consequently, the pH at equivalence point was measured and the value was 10.99. Calculate the pH if the volume of the NaOH added is less than 8.16ml of the volume at equivalence point.
