Weband causing water to have high surface tension. 6. At water’s surface, its molecules are only attracted to the water molecules below and to the sides of them, as there is only air above these molecules. So, the surface molecules of a body of water are pulled down, creating a much more stable, stronger arrangement. • Inquiry Discussion 2 WebDetergents can align at aqueous/non-aqueous interfaces, resulting in reduced surface tension, increased miscibility, and stabilization of emulsions. Additional detergent applications include: Extraction of DNA and RNA. Solubilization of specimens for diagnostic applications. Cell lysis. Liposome preparation. beda agama lirik

WebDetergent molecules have two ends, one hydrophobic end, repelled by water and one hydrophilic end, attracted to water. In water detergent molecules on the surface are aligned with their hydrophobic ends away from the surface. They break the surface and thus lower the surface tension. Other detergent molecules are dispersed throughout the water. WebIt measures the difference between the surface energy (per unit area) of the substrate when dry and wet: S = [E substrate] dry - E substrate] wet or S = γ solid - (γ liquid + γ solid-liquid) S > 0: Total wetting If the parameter S is positive, the liquid spreads completely in order to lower its surface energy.
