| Abstract: | Measurements of surface tension have been performed to determine the effects of both temperature and concentration on the
surface tension of aqueous solutions of D-Sorbitol, potassium chloride, and ammonium chloride. A differential capillary-rise
method was employed for the measurements. The results showed that the surface tension of test solutions increased as the temperature
decreased and that the surface tension of chloride solutions increased with an increase in its concentration, while for D-Sorbitol
solution the surface tension decreased with increasing concentration. Correlation equations for the surface tension of three
aqueous binary solutions as a function of temperature and concentration were determined. |
