Abstract
The effect of various solutes on the strength of hydrophobic interaction in aqueous solutions has been determined by a method devised previously for this purpose. The solubilities of methane and ethane in aqueous solutions of electrolytes and nonelectrolytes were measured in the range of temperatures between 5 and 25°. These data have been used to compute the standard free energy, entropy, and enthalpy of solution of methane and ethane in these solutions. It is found that most added solutes increase the strength of hydrophobic interaction. An opposite effect has been noted by some nonelectrolytes which are presumed to enhance the structure of the solvent.
