100 mL x 0.1M HAc = 10 mmoles.
100 mL x 0.1M NaAc = 10 mmols.
1 mL x 0.1M NaOH = 0.1 mmol.
-----------------------
......HAc + OH^- ==> Ac^- + H2O
I.....10.....0.......10
add........0.1..............
C...-0.1..-0.1.......+0.1
E.....9.9...0........10.1
Substitute the equilibrium values into the Henderson-Hasselbalch equation and solve for pH.
