You are titrating 85.0 mL of a 1.44 M formic acid solution with a 0.625 M potassium hydroxide solution.
a. What is the pH of the formic acid solution before you begin titrating?
b. What is the pH after 50.0 mL of the potassium hydroxide solution has been added?
c. What volume of potassium hydroxide is needed to reach the equivalence point?
d. What is the pH at the equivalence point?
e. What is the pH when an additional 25.0 mL of potassium hydroxide has been added (beyond the equivalence point)?
