Potentiometric and Spectroscopic Studies with Chromium(III) Complexes of Hydroxysalicylic Acid Derivatives in Aqueous Solution
Chromium is a first row transition element in the periodic table. It may resembles the group 16 elements of the oxygen group but only in the acidity of the trioxide and in its covalent nature. Cr(III) with its d configuration forms thousands of inert complexes; an important characteristic of these complexes, in aqueous solutions, is their relative kinetic inertness. The radius of Cr(III) is 0.7...

15 صفحه اولAbsorption Spectroscopic Determination of Solubility of Alloxazine in Aqueous Solutions
The solubility of alloxazine in aqueous solution at pH 4 (10–4 molar HCl) and pH 10 (10–4 molar NaOH) at room temperature is determined by absorption spectroscopic characterization. Knowledge of the solubility is needed for sample preparation and quantitative spectroscopic solution characterization. Samples of different in-weight concentration were prepared and absorption spectra were measured ...
متن کاملSpectroscopic studies of solutes in aqueous solution.
Absorption and fluorescence characteristics of aqueous solutions of salts, sugars, and amino acids were studied using UV-vis spectroscopy and spectrofluorometry. Motivation stemmed from unanticipated absorption spectral and fluorescence features of the "exclusion zone" seen adjacent to various hydrophilic surfaces. Those features implied a structure distinct from that of bulk water (Adv. Colloi...
متن کاملSuccinic acid in aqueous solution: connecting microscopic surface composition and macroscopic surface tension.
The water-vapor interface of aqueous solutions of succinic acid, where pH values and bulk concentrations were varied, has been studied using surface sensitive X-ray photoelectron spectroscopy (XPS) and molecular dynamics (MD) simulations. It was found that succinic acid has a considerably higher propensity to reside in the aqueous surface region than its deprotonated form, which is effectively ...
