 Method/Apparatus/Procedure:
   Trichloromethane was introduced from a microburet into an aqueous solution of rubidium chloride which contained octanoic acid as indicator. The mixture was vigorously stirred. The pH of the solution at first remained constant right up to the appearance of  a second phase, i. e., up to the saturation of the aqueous phase with trichloromethane, after which the pH began to rise. The solubility was calculated from the volume of the aqueous phase and the volume of trichloromethane used for the saturation.
