A) If a volume of 21.00 ml of NaOH solution is required to reach the equivalence point in titration of a weak acid, what relationship exists between pH and pKa of the acid after 9.00 ml of the NaOH solution has been added?
B) If a volume of 24.00 ml of NaOH solution is required to reach the equivalence point in titration of a weak acid, what relationship exists between pH and pKa of the acid after 8.00 ml of the NaOH solution has been added?
