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...
