Write the Henderson-Hasselbalch equation for a solution of propanoic acid (CH3CH2CO2H, pKa = 4.874 ) using HA, A–, and the given pKa value in the expression.
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?
