Thermodynamic study of ion- association in KNO3 solution in the mixed solvent (water +methanol)
The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...
متن کاملThermodynamics of Ion Association in the Saturated Solution of The Mixed Solvent (methanol+water) and Ion Pairing at 25.0°C
In this study, the ion association phenomenon in the saturated solution of KCl in the mixed solvent(methanol+water) was studied. The solubility of this compound in the mixed solvent (methanol+water by value percent of methanol = 60%), and in the presence of various molarities of NaNO3 wasdetermined by the solvent evaporation method at 25.0°C. The results enable us to estimate the valueof thermo...
متن کاملNa–Cl ion pair association in supercritical water
Molecular dynamics simulations of supercritical electrolyte solutions with three different ion–water models are performed to study the anion–cation potential of mean force of an infinitely dilute aqueous NaCl solution in the vicinity of the solvent’s critical point. The association constant for the ion pair Na/Cl and the constant of equilibrium between the solvent-separated and the contact ion ...
متن کاملAssociation between Dietary Diversity Score and Nutrient Adequacy in Patients with Calcium Oxalate Kidney Stone
Background: Nephrolithiasis is a global health problem that is growing exponentially in the developed and developing countries. This study aimed to determine the dietary diversity score (DDS) and its association with nutrient adequacy in patients with calcium oxalate kidney stone. Methods: The present cross-sectional study was conducted on 276 male patients with calcium oxalate kidney stone. Th...
متن کاملThermodynamics of the solubility of potassium nitrate in the mixed solvent, Ethanol+Water, and the related Ion-association
Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...
