Abstract |

The search on the following main parts:
Part I: study of spectral evidence under study: independent study of the behavior of spectral evidence free, and include the results of spectral measurements in the ultraviolet region of the different concentrations for each directory separately from the binaries pyridine, when temperatures 45,35,25, ˚ C in the three severity ion over the sodium chlorate or sodium chloride (1 ر 3.5 Molara t), has been appointed constants absorption spectrum of each of these guides at each end for super absorption and at each temperature and ionic intensity. Was written as well as measuring the absorption spectral evidence for a three-pyridine at a temperature of 25 ˚ C and set the constants at the absorption spectrum has two ends of the bones absorb.
Part II: Stability constants of complexes with the elements of evidence:
In this part was measured absorption spectroscopy in the ultraviolet region of the mixture of concentration constant of the guide, with concentrations varying from cations (magnesium, barium, and nickel), in the intensity of ionic 5 R. Moeller, of perchlorate, sodium or sodium chloride and at temperatures of 54.35 , 25 ˚ C. Has been making these measurements in some cases of magnesium with a manual 2.2/.4, 4 / pyridine when the intensity of binary ionic R. 8 instead of 5 Molar Molar t was measured as well as absorption spectroscopy and magnesium complexes of three pyridine at 25 ˚ C.
Been in the search set some parameters of thermodynamics, such as the change in heat content, and the change in anthropic, and the change in Gibbs free energy. Found that the evidence for the four binaries pyridine did not give the equilibrium constants of the Union with all the appropriate ion of magnesium and nickel. Found an exact match between the fixed ion balance, the Union of magnesium sulfate which was obtained using a guide with a three-pyridine was obtained in other ways. |
