    The henderson hasselbalch equation is given by: pH=p Ka + log [ A - ] [HA] where [A-] is the molar concentration of a conjugate base. and [HA] = molar concentration of some weak acid. Now, you can start off by writing a chemical equation of propanoic acid and dissociation of it's hydrogen. Can you try it now?
