Here is what you need to know. Use this information to make your sentences.

The Henderson-Hasselbalch equation is
pH = pKa + log (base)/(acid)
Knowing what pH you want and the pKa of the acid, calculate (base) and (acid) you need to prepare the pH you want. base is propanoate. acid is propanoic acid.
