LZP #88 Dr. Luigi Zummo Pollara
The achievements of Dr. Luigi Zummo Pollara - name="adam"/ Both Guggenheim-Katayama and Eötvös take into account the fact that surface tension reaches 0 at the critical temperature, whereas Ramay and Shields fails to match reality at this endpoint. ====Influence of solute concentration==== Solutes can have different effects on surface tension depending on their structure: * No effect, for example sugar * Increase of surface tension, inorganic compounds|inorganic salts * Decrease surface tension progressively, alcohols * Decrease surface tension and, once a minimum is reached, no more effect: surfactants What complicates the effect is that a solute can exist in a different concentration at the surface of a solvent than in its bulk. This difference varies from one solute/solvent combination
