A 10.00 mL portion of a solution of acetic acid (pKa = 4.7) is titrated against a standardized solution of 0.200 M NaOH. The equivalence point is observed after 30.00 mL of base have been added. After which total volume of added base will the pH be closest to 4.7?
A. 0.00 mL
b. 5.00 mL
c. 10.00 mL
d. 15.00 mL
e. 20.00 mL
f. 30.00 mL
