Question

What is lyophobic colloid? ​

Answer 1

Answer:

Lyophobic colloids are liquid hating colloids (Lyo means solvent and phobic means hating). When these colloids are mixed with the suitable liquid, a very weak force of attraction exists between colloidal particles and liquid and system does not pass into colloidal state readily...

• What is lyophobic colloid?

$\sf\underbrace\orange{Required\: Answer: }$

A Lyophobic Colloid is a substance that contains large molecules that do not properly dissolve in liquids. The term Lyophobic comes from “Lyo” which means solvent and “Phobic” which means hating. When such colloids dissolve in a liquid, a very weak attraction force exists between the liquid molecules and colloidal particles and system does not readily become a colloidal solution.

$\sf\underline\purple{Additional\: Information: }$

lyophobic colloid an unstable colloid system in which the disperse phase particles tend to repel liquids, are easily precipitated, and cannot be redispersed with additional solvent.

As lyophobic colloidal particles do not mix with a liquid, lyophobic solutions are difficult to prepare and special techniques are used to ensure that the colloidal particles are dissolved in the liquid. All lyophobic solutions are generally less stable as they have a weak force of attraction between the colloidal particles and the liquid particles. Even if a small quantity of electrolyte is added in such solutions, they become very unstable and tend to form a precipitate. Lyophobic solutions are irreversible in nature.

Lyophobic (liquid hating) Colloids consist of the phases, which do not interact between each other.

Dispersed phase in lyophobic colloids is not solvated by the dispersion media. Lyophobic colloids are prepared by mechanical agitation, which is required because of high interfacial energy of the dispersed particles. Lyophobic colloids are thermodynamically unstable. Their dispersed particles have a tendency to aggregation or coalescence.Thermodynamic stability of lypophobic colloids may be increased by an addition of relatively small amount of surface active substances (surfacants) lowering the interfacial energy of the system. Aerosols and most of water based colloids with inorganic dispersed phase are lyophobic. Some of lyophobic colloids possess lyophilic properties (eg. hydrosols of silica and alumina).
