Solubilities of KCl and NaCl in binary mixed solvents of CH_3OH-DMF and CH_3OH-DMSO with mole fraction of components from 0 to 1 were measured at 288, 303, 313 K for KCl and 278, 288, 298, 303 and 313 K for NaCl. A plot of solubility of KCl and NaCl vs composition of solvent shows a maximum. The coefficient of solubility with temperature for KCl is positive and for NaCl is negative. The transfer free energy and entropy of KCl and NaCl from pure methanol to mixed solvents were evaluated from the measurements, thus the structure property of solution, the effect of salt on it, the ionic solvation and the tendentiousness of solution were discussed preliminarily.
