Non- Ideality and Ion-Pairing in Saturated Aqueous Solution of Lithium Carbonate at 25°C
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...

متن کاملA Raman spectroscopic study of arsenite and thioarsenite species in aqueous solution at 25°C
The Raman spectra of thioarsenite and arsenite species in aqueous solution were obtained at room temperature. Solutions at constant SAs 1 SS of 0.1 and 0.5 mol kg were prepared with various SS/SAs ratios (0.1–9.0) and pH values (y7–13.2). Our data suggest that the speciation of As under the conditions investigated is more complicated than previously thought. The Raman measurements offer evidenc...
متن کاملDissociation of Some Substituted Phenols in 50-Percent Aqueous Methanol as Solvent
The dissociation constants of the following substituted phenols in 50 wt percent methanol have been measured at 25 °C: o-nitrophenol, p-nitrophenol, 4-methyl-2-nitrophenol, 2,6-di chlorophenol , pentachlorophenol. The respective values found, expressed as pK values, are 7.91" 7.692 , 8.28" 7.680 , and 5.27.. The dissociation cons tants of 4-methyl-2-nitrophenol and pentachlorophenol, again exp ...
