- Consider a titration of 250 mL 0.15 M acetic acid (Ka = 1.8 x10-5) with 0.10 M KOH.
- What is the pH of the acetic acid solution (ie: before the titration has begun?)
- What is the pH after adding 25 mL of 0.10 M KOH?
- What is the volume of base needed to reach the equivalence point?
- Is the pH at equivalence point acidic, basic, or exactly neutral?
- What is the pH after 500 mL of KOH has been added?
