1. Before addition of any base
2. after addition of 30.0 mL of base

HA ==> H^+ + A^=
Set up an ICE chart for acetic acid, substitute into Ka expression and solve for H^+, then convert to pH.
2. Use the same ICE chart and add 30.0 mL x 0.1M NaOH and recalculate the H^+ and pH. Don't forget the dilution by the extra 30.0 mL of NaOH>
