For the titration of 25.0 mL of 0.100 M propionic acid, C2H5COOH, with 0.150 M NaOH, answer the following and construct a titration curve. (Ka = 1.3*10^-5 pKa = 4.89)

1. How many milliliters of base are required to "neutralize" the acid?

2. What is the pH of the propionic acid solution before any base is added?

3. What is the pH at the half-stoichiometric point?

4. What is the pH when 95% of the base required to reach the stoichiometric point has been added?

5. What is the pH at the stoichiometric point?

6. What is the pH when 105% of the base required to reach the stoichiometric point has been added?
