Acid-base properties of 2,4-dihydroxy benzaldehyde-3 [6-phenyl] pyridazinyl hydrazone [DBP3H] formation constants of some of it's complexes

ABSTRACT

The objective of this study was to present some details of the synthesis, properties and the analytical behavior of the new reagent; namely, 2,4-dihydroxy-benzaldehyde-3 [6-phenyl] pyridazinyl hydrazone [DBPzH] and its possible applications for the determination and detection of some cations. The finding was based on the evaluation of the dissociation constant of the reagent, the composition and formation constants of the complexes by spectrophotometric and potentiometric methods:
