Abstract: This paper reports our measurements of the solubility of KCI in the mixtures of methanol-benzene, -toluene, -cyclohexane, -carbontetraehloride at 278.16, 288.15, 298.15, 308.15 K. These data can be expressed by
log(S_o/S_m)=kx_Ne (1)
and
log(S_o/S_m)=k_φφ_(Ne) (2)
where S_o and S_m are the solubilities of salts in pure methanol and mixed solvent, respectively, x_(Ne) and φ_(Ne) are the mole fraction and volume fraction of nonelec- trolytes in the mixed solvent,respectively, k_φ is called the second medium cons- tant. ...
