What are lyophilic and lyophobic sols? Give one example of each …

WebCoagulation of lyophobic solutions: Lyophobic sols are less stable than lyophilic colloid. Hence they are more easily coagulated. The stability of lyophobic sol is only due to the charge on the colloidal particles. This factor can be removed by adding only electrolytes. This was just a brief layout of the coagulation of lyophilic and lyophobic ... WebSince particles of dispersed phase in lyophilic sols have an affinity for the particles of dispersion medium, these sols are more stable as compared to lyophobic sols. Two factors responsible for the stability of sols are – charge and the solvation of the colloidal particles by the solvent. Stability of lyophilic sols is primarily due to WebHigher affinity of Lyophilic sols towards water makes it hydrated and results in higher viscosity. Any solution with a higher viscosity, leads to a decrease in surface tension than the Dispersion medium. So, the Surface tension of Lyophilic sols is lower than that of H 2 O and more in the case of Lyophobic sols. So, option[B] is incorrect. いきがる 英語

Web8 apr. 2024 · The lyophilic sols are more stable than lyophobic sols because lyophilic sols are solvent loving whereas lyophobic sols are solvent hating. Also in lyophobic sols, the dispersed phase shows no attraction for the solvent or the medium. And as we know, solvation is the most important property for the colloidal particles. Web5 ian. 2024 · Lyophilic sols are more stable than the lyophobic sols. The stability of lyophilic sols is due to the solvation i.e. a protective layer is created around the colloidal particles by the dispersion medium in which they are dispersed. Coagulation of lyophilic sols, there are two factors responsible for the stability of lyophilic sols.
