Lyophilic sol
WebLyophilic sols are those in which the dispersed phase and dispersion medium (water) have a high affinity. A colloidal solution made by dissolving starch in water, for example. The dispersion medium in this colloidal solution is water, and the dispersed phase is starch. This sol is made by boiling water to 100 degrees Celsius and dissolving ...

WebThese sols are formed by substances like gums, starch and proteins. Lyophilic sol can be easily prepared by directly mixing colloid with the liquid. The lyophilic colloids are highly viscous in nature and have higher viscosity than that of the medium (water). The surface tension of these sols is less than that of dispersion medium (water). WebLyophilic (“liquid-loving”) sols are more stable and more closely resemble true solutions. Many sols are intermediate between lyophobic and lyophilic types. Compare gel. sol, in physical chemistry, a colloid (aggregate of very fine particles dispersed in a continuous medium) in which the particles are solid and the dispersion medium is ...
Web8 mar. 2024 · Hint: Lyophilic sols are more stable than lyophobic sols because lyophilic the lyophilic colloids are highly solvated. Lyophilic sols are guards of lyophobic sols. Complete answer: We have studied that lyophilic sols are very stable in nature. This is due to strong interaction forces between the dispersed phase and dispersion medium. Web8 apr. 2024 · These sols are formed by special methods and are generally unstable. Gold sol being a sol of gold (Au) metal is thus, a lyophobic sol. Metal sols are generally negatively charged.
