WebJul 20, 2024 · 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 (e.g. water vs. gasoline) or solutes in the liquid (e.g. surfactants like detergent), each solution exhibits differing surface tension properties. WebApr 17, 2015 · That happened because the detergent molecule reduces the attraction of water molecules to each other by disrupting their ability to form hydrogen bonds. The addition of detergent reduced the surface tension of the water. The reduction of surface tension by detergents is what allows water-detergent solutions to form large bubbles.
