The structure of oximes was proved by using available physical methods included (Infrared, Ultraviolet spectra and melting points). The aim of this study was to evaluate the ionization constant by conductivity method at different temperatures. The thermodynamic parameters namely (∆G, ∆H, ∆S) of ionization reaction of these oximes as determined and discussed in details. The antibacterial activity of these oximes was tested against some bacteria. Optimized structure, boundary molecular orbitals (HOMO and LUMO) and global reactivity descriptors were analyzed by DFT calculations.

In the present study we have measured the electrical conductivity of Mn(II), Ni(II), Fe(II) complexes with Arginine in aqueous solutions of mono and di saccharide at (310.16 K), The data were analyzed using Lee-Wheaton(LW) conductivity equation for asymmetrical electrolytes. The conductivity parameter: ionic conductivity (λ) association constant (KA) and the average distance parameter between the ions (R) at the best fit values of the standard deviation ( ) have been calculated, The results are discussed depends on the basis of solvent effect on the conductivity parameter of these complexes. Walden products have also been calculated for each solvent composition.

The aim of this work is to measure the electrical conductivity of Co (II) and Ni (II) complexes with 4-amino antipyrine in mixtures of different percentages of methanol and water at different temperatures. The data were analyzed using the Lee-Wheaton equation for unsymmetrical electrolytes, the conductivity parameters: ionic equivalent conductivity λM +2, association constant KA, and the distance parameter R are calculated. The ionic equivalent conductivity λM +2, increases with increasing temperature, which may attributed to the breaking of hydrogen bonds between solvated ion. Association constant KA increase with increasing temperature, which assumed the presences of simple coloumbic interactions between hard sphere ions in continuous medium. The distance parameter R are calculated at the bist fit values of standard deviation σΛ. Thermodynamic parameters from the relation between LnKA and 1\T were calculated to examine the nature of interaction. Walden product were calculated which show the variation depending on electrochemical equilibrium between ions and the solvent molecules with the composition of the mixed polar solvents.
