چکیده مقاله :
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 extended Debye- /Rickel law,IC:p =[Li12 [CO 3-2 ify_ , revealed a great difference. The difference has satisfactorily been explained using acombination of Debye-flackel law and Ion-Association Theory.
