POTENTIOMETRIC AND CONDUCTIMETRIC STUDIES OF CHEMICAL EQUILIBRIA FOR PYRIDOXINE HYDROCHLORIDE IN AQUEOUS SOLUTIONS: SIMPLE EXPERIMENTAL DETERMINATION OF PKA VALUES AND ANALYTICAL APPLICATIONS TO PHARMACEUTICAL ANALYSIS

POTENTIOMETRIC AND CONDUCTIMETRIC STUDIES OF CHEMICAL EQUILIBRIA FOR PYRIDOXINE HYDROCHLORIDE IN AQUEOUS SOLUTIONS: SIMPLE EXPERIMENTAL DETERMINATION OF PKA VALUES AND ANALYTICAL APPLICATIONS TO PHARMACEUTICAL ANALYSIS

The combination of two low-cost classical procedures based on titrimetric techniques is presented for the determination of pyridoxine hydrochloride in pharmaceuticals samples. Initially some experiments were carried out aiming to determine both pKa1 and pKa2 values, being those compared to values of...
