Abstract
In the present work an undergraduate laboratory practice is described corresponding to both experimental and computational methods used in potentiometric equilibrium constants determinations. As an example of these determinations the system formed by Cu(II) and D-galacturonic acid was selected. Both the deprotonation constant for the ligand and the equilibrium constants for the metal chelates were determined by using the program BEST.
