SUMMARY
The discussion centers on calculating the volume of 0.200M HCl required to create a buffer solution with a pH of 3.37 from 250.0ml of 0.300M sodium mandelate. Participants confirm the use of the Henderson-Hasselbalch equation, pH = pKa + log [A-/HA], while addressing the complete dissociation of HCl and its role in protonating sodium mandelate. The assumption is made that the protonation occurs stoichiometrically, allowing for the determination of the necessary HCl volume.
