25.00 mL of .0653 M acid is titrated with our stock solution of .06964 M NaOH. 25.5 mL of NaOH is required to reach the equivalence point. If the acid is a strong acid, calculate the pH after the following volumes of NaOH have been added. Show work.

a. 0 mL NaOH; pH=
b. 50% of NaOH volume required to reach the equivalence point: _mL NaOH; pH=
c. At the equivalence point: _mL NaOH; pH=
d. 125% of the NaOH volume required to reach the equivalence point: _mL NaOH; pH=​
