| Abstract: | The freezing-point depression of the ternary systems water-alkali halidesalcohols was measured with a precision Advanced Instrument osmometer. From the corresponding freezing-point depression of the binary systems the salting-out constantsks were calculated. The effect of ionic size was investigated withtert-butanol, and the effect of alcohol chain length with NaCl. The trends ofks with ionic size are similar to those of typical nonelectrolyte systems, andks varies linearly with the volumes of the normal alcohols. |
