Question 1
(a) According to your experimental data, what volume of 0.10 M NaOH represents the half-equivalence (a.k.a. half-neutralization) point in this titration?
(b) What is the pH of the solution at the half-neutralization point?
(c) Using this info, what is the experimental pKa for acetic acid in this reaction? Explain your answer.
(d) Using the pKa value above, what is your experimental Ka for acetic acid?

Question 2
Look up the accepted “actual” Ka value for acetic acid. How does your value compare? Calculate the percent error for your experimental value.

Question 3
What are some possible sources of error in your experiment, and how could you account for these sources in future experimental runs? Discuss in detail.
