Electrical Behaviour of Association Phenomena of Tetra aqua-1,10-phenanthroline Iron (II) Chloride in Methanol-Water Mixtures at Different Temperatures

Conductivity Study of Tetra Aqua -1,10- Phenanthroline Zinc(II) Chloride in Aqueous Methanol Mixture at Different Temperatures

“…Furthermore, K A is increase from 80%to 60% of methanol because of increasing H _ bonding due to increasing water percentage and increasing viscosity which play an important role. Similar observation have also been noted for some electrolytes in the same mixed solvents (Hameed et al, 2008, Hameed et al, 2007 and in other mixed solvents (AL-Mustawi, 2002) and this may be attributed to the selective solvation of ions besides the solvodynamic viscose force ( Das and saha, 2000). The results of the distance paramenter R are large according to the following two effects: firstly isolated ions (in particular the cation) will tend to be surrounded by extensive solvent shells or the existence of these dielectrically saturated regions give rise to a repulsive force between the ions when ) 9 ( ) 10 ( they come into close approximately.…”

“…The characteristics of metal chelate electrolytes and their solute-solvent interaction concerning charge, size and chemical properties of liquid have been elucidated by the study of the electronic spectra (Fukuda and Sone, 1972), racemization, (Meter and Newmann, 1976), optical resolution (AL-Mustawi, 2002), viscosity, molar volume (Tamingo, 1975) and conductivity (Newmann et al, 1979). The electrical conductivities of [Fe(1,10-phenanthrolin) (H 2 O)]Cl 2 in methanol-water mixture at different temperatures (288.15 _ 308.15k) have been studied (Hameed et al, 2008 ).…”

Electrical Conductance And Theoretical Study Of Glutamic Acid In Different Solvents at 310.16k

“…What supports the concert of the theoretical and practical results is that these results coincide with the entropy values as they were maximum value in ethanol, methanol, and water, respectively. In addition to the difference in (MV) values, the difference in the molecule geometry can also be observed in the solvents as shown in Table (3)(4), which conforms with all results having from this study.…”

“…However, only the conductance of single symmetrical electrolytes has been interpreted and far less attention, either functional or theoretical, has been paid to unsymmetrical electrolytes (especially associated ones) or to the electrolyte mixture. In the past few decades, some studies have been carried out on unsymmetrical electrolyte solutions [3]. In combination with refined experimental methods, computer simulations nowadays help to fill the above knowledge gaps.…”

دراسة توصيلية وحسابية للكلورامفينيكول في مذيبات ودرجات حرارية مختلفة

“…In the scientific studies, it is necessary to know the behavior of electrolytes in solution so the electrical conductivity studies , one of the most important ways to show the ion-ion and the ion-solvent interaction is by noting the properties for conductivity with ions movement 10 . Furthermore, the effect of temperature on the conductivity measurements for the electrolyte solution with different temperature can give more information about the kind of interaction 11 .…”
