Buffers Sheet Report
Please refer to the data you collected in QUESTION 1 to explain the observations.
1. In (a) you had only acetic acid and the pH was low. Explain.
2. In (b) you had only sodium acetate and the pH was high. Explain.
3. In (c) and (d) you made buffered systems. Compare the values obtained to the
pKa = 4.75 (which would be the pH if you had equal amounts of acetic acid/sodium
acetate) and explain the pH values you obtained. Explain these effects separately (do
not try to combine answers.)
4. In (e) and (f), you took solution (d) and added a strong acid or a strong base.
Explain what happened to the pH and why it happened. Be sure to start with the pH
you obtained in (d) to discuss the effects in (e) and in (f). Explain these effects
separately (do not try to combine answers.)
