What are lyophilic colloids?

Answer 1

Lyopobic colloid is a colloidal dispersion whereby the dispersed phase is solvent hating .i.e little interaction between the dispersed phase and the continuous phase. Lyophobic colloidal particles are not readily solvated because the continuous phase prefer to interact with one another than be involved in solvating the dispersed particles. Lyophobic colloidal dispersion does not form spontaneously when the dispersed particles and the continuous phase are brought together. The dispersed particles will tend to aggregate i.e thermodynamically favourable. However this is not pharmaceutically favourable. Dispersion method and condensation method are two methods involved in manufacturing lyophobic colloids. If the continuous phase is water, it is also called hydrophobic colloids.

Answer 2

Each particle of lyophilic colloids is solvated - coated with a monomolecular layer of the dispersion media.

Dispersed particles of intrinsic shape and some polymer molecules may entrap additional molecules of the dispersion media resulting in higher solvation of the colloid system.

Due to solvation lyophilic colloids are more viscous than the dispersion media.

If the dispersed polymer molecules are cross-linked they form a network structure, in which all the dispersion media is mechanically entrapped. Properties of such colloids (gels) are similar to those of solid.

Formation of lyophilic colloids is spontaneous (mechanical agitation is not required). The colloids are thermodynamically stable. The average size of the dispersed particles is determined by the value of the interfacial tension and the temperature.

Answer 3

Lyophilic colloids are colloidal systems in which the dispersed phase has a great affinity for the dispersion medium, allowing for stable dispersion without the need for stabilizing agents. These colloids form spontaneously due to strong interactions between the dispersed particles and the medium, resulting in a stable and homogeneous mixture. Examples include starch solutions and proteins like Gelatin.

Answer 4

luophilic colloids are coloidal system that prodece stabledispersionbetween colloidal particles and liquid

Answer 5

LYOPHILIC is more stable than Lyophobic which is water-hating.I just heard this topic when we watched at our school's AVR.Hope helps!

Answer 6

`Lyo` means solvent and `phile` means to love so lyophilic colloidal particles have a great attraction towards solvent molecules so are stable in solution.

Answer 7

A lyophilic colloid is a macromixture that is predominately liquid loving but also has other latent properties, like viscosity, solidity, or turbidity, for instance like milk.
