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...

the solubility of cdf2 in the mixed solvent (water(1)+ethanol(2)) with mass fraction, w1 = 0.9,was determined by using solvent evaporating method in the presence of various concentrations(0.100, 0.200, 0.300, 0.400, 0.500, 0.600, 0.800 and 1.500 mo1.1)) of naci at 25°c. the values ofsolubility and solubility product constant of cdf2 in the mixed solvent were evaluated at zero ionicstrength upon...

the solubility of k2so4 in water at 25°c was determined. comparing the value ofthermodynamic solubility product constant, ksp(th), (ksp(th) = exp (-δgodiss rt) of the mentionedsalt to the value of concentration solubility product, ksp(c) which is obtained from the observedsolubility, s/mol-1, ksp(c) = 4s3, revealed a great difference. the difference can be satisfactorilyexplained using debye- h...

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...

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...

The solubility of K2SO4 in water at 25°C was determined. Comparing the value ofthermodynamic solubility product constant, Ksp(th), (Ksp(th) = exp (-ΔGodiss RT) of the mentionedsalt to the value of concentration solubility product, Ksp(c) which is obtained from the observedsolubility, s/moL-1, Ksp(c) = 4s3, revealed a great difference. The difference can be satisfactorilyexplained using Debye- H...

using solvent evaporating and atomic emission spectrophotometric methods, the solubility of li2co3 in waterat 25°c was determined. comparing the value of thermodynamic solubility product constant, ksp(th),(ksp(tn) = exp(—ag.ss/rt)) of the mentioned salt to the value which is obtained from the observed solubility,shnoll-1 , and activity coefficients, f+ and f, which are estimated upon the extend...

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...
