TL;DR: The acid–base properties of two bifunctional 3-hydroxy-4-pyridinone ligands and their chelating capacity towards Zn2+, an essential bio-metal cation, were investigated in NaCl aqueous solutions by potentiometric, UV-Vis spectrophotometric, and 1H NMR spectroscopic titrations and the determination of protonation and stability constants showed accordance with the data obtained from the different analytical techniques used.

TL;DR: In this paper, voltammetric measurements on the interactions between tin(II) and the most important natural inorganic ligands, OH−, Cl−, F−, CO 3 2 -, SO 4 2 - and PO 4 3 - were reported.

TL;DR: In this paper, the self-interaction (ki) parameters from solubility and distribution data and the dimerization constant from the protonation constants in the same experimental conditions, were calculated.

TL;DR: In general, phytate results in a quite good sequestering agent toward all three cations in the whole investigated pH range, but the order of pL(0.5) depends on it, and the dependence on pH was modeled using some empirical equations.

TL;DR: This kind of systematic studies, where a series of ionic media is taken into account in the determination of various thermodynamic parameters, is useful for the definition of some trends in the thermodynamic behavior of glutathione in aqueous solution.
