TL;DR: In this paper, rate constants for tris(5-nitro-1,10-phenanthroline)iron(II) have been determined in a wide range of binary aqueous mixtures.
Abstract: Rate constants for the aquation of tris(5-nitro-1,10-phenanthroline)iron(II) have been determined in a wide range of binary aqueous mixtures. The results are presented and discussed in terms of correlation diagrams involving the excess molar Gibbs function of mixing for the binary mixtures. The behaviour of this iron(II) complex is compared and contrasted with that of t-butyl chloride. The possible advantages of this mode of treatment of kinetic results are outlined.
TL;DR: In this paper, the thermodynamic parameters of ionization (pK, ΔG, ΔH and ΔS) of Kojic acid have been evaluated potentiometrically.
Abstract: The thermodynamic parameters of ionization (pK, ΔG, ΔH and ΔS) of Kojic acid have been evaluated potentiometrically. The pK value decreases with increase in temperature and has a linear relationship with the concentration of dioxane. The process of solvation and aquation is discussed. The mechanism of complexation between Kojic acid and some transition metals is discussed and the log β value is calculated.
TL;DR: In this article, the biological effect, aquation, and kinetics of bis(2-aminobenzothiazole)dichlorocobalt(II) complex by periodate in aqueous acidic solutions were studied.
Abstract: The biological effect, aquation, and kinetics of oxidation of bis(2-aminobenzothiazole)dichlorocobalt(II) complex by periodate in aqueous acidic solutions were studied. The complex exhibited a broad resistance toward the studied pathogens. The average value of the aquation constant was calculated spectrophotometrically as 2.55 × 10−5 mol2 dm−6. Kinetics of the oxidation reaction showed first-order dependence on each reactant concentration and increased by increasing pH over the 3.80–4.80 range, 35–50°C, and decreased by increasing the ionic strength over the 0.1–0.5 mol dm−3 range. The polymerization of acrylonitrile was taken as an evidence for an inner-sphere mechanism through the formation of free radical intermediates of Co(III) complexes, which were slowly converted to the final Co(III)products.
