WebIn an aqueous environment, the hydrophilic portion is water-loving and polar, whereas the hydrophobic part of the surfactant is water-hating and relatively non-polar. Surfactants reduce the surface tension of water by adsorbing at the interface. WebSurface Tension. Surface tension is the energy, or work, required to increase the surface area of a liquid due to intermolecular forces. Since these intermolecular forces vary depending on the nature of the liquid …
