The henderson hasselbalch equation is given by: pH=pKa+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?
