Suppose you are asked to prepare an acetic acid/acetate buffer solution that has a final pH of 5.2. What ratio of acetic acid to acetate ions do you need in solution to reach a pH of 5.2? (pKa of acetic acid is 4.76)
Added by Marc L.
Step 1
We know that the pH of a buffer solution can be calculated using the Henderson-Hasselbalch equation: pH = pKa + log ([A-]/[HA]) Show more…
