Abstrakt: The solubilities of capric, lauric, myristic, palmitic, and stearic acids in water at 25° and 50°C. were determined by use of conductivity measurements. Correction was made for carbon dioxide; and total solubilities, together with the concentration of dissociated and of undissociated acid were calculated. Their solubilities range from 359×10 M for capric acid to 2.1×10 M for stearic acid at 25°C. The solulility of laric and myristic is approximately doubled by an increase of temperature from 25° to 50°C., that of capric, palmitic, and stearic acids increases by 25 to 40%.
