Differbetween
In lyophilic colloids, the particles of the dispersion medium have a strong affinity for the particles of dispersed phase. ... In lyophobic colloids, the particles of the dispersion medium and the dispersed phase do not interact with each other. Hence there is no solvation of the dispersed phase by the dispersion medium.

What is difference between Lyophilic and lyophobic colloids?
Lyophobic colloids: Here 'Lyo' means 'solvent' and 'phobic' means 'to hate'.
...
Complete step by step answer:
| Lyophilic colloids (liquid loving colloids) | Lyophobic colloids (liquid hating colloids) |
|---|---|
| 2) Dispersion phase has high affinity for dispersion medium. | 2) Dispersion phase has low affinity for dispersion medium. |
What are Lyophilic and lyophobic colloids explain with one example?
Examples are: Sol of gum, gelatine, starch etc. are lyophilic sols. On the other hand if dispersed phase tends to repel (i.e., dislike or hatred) dispersion medium, the resultant sol is termed as lyophobic sol. Examples are: Sols of metals, metal hydroxides, metal sulphides etc.
What is the major difference between Lyophilic and Lyophobic Sols?
Difference between Lyophobic and Lyophilic sol
| Lyophobic sol | Lyophilic sol |
|---|---|
| Irreversible | Reversible |
| They are less stable and get coagulated by adding electrolytes by heating or by agitating. | They are quite stable and are not easily coagulated by the addition electrolytes |
What is Lyophilic colloids and lyophobic colloids?
i) Lyophilic Colloids: These are the colloidal solutions in which dispersed particles have strong affinity for dispersion medium. These sols are stable and reversible. ... ii) Lyophobic Colloids: There the dispersed phase has no affinity for the dispersion medium. These are unstable sols and are irreversible.
What are associated colloids give an example?
The formation of the micelles occurs above a particular temperature called the Kraft temperature (Tk) and also above a specific concentration called the critical micelle concentration. These colloids can be reverted by diluting it. Examples of some associated colloids are soaps and synthetic detergents.
Is milk a Lyophilic colloid?
Milk is the colloid in which solid oil globules remain suspended in a water-based liquid system. We can separate the components of the milk, so milk is a lyophilic colloid.
How are sols classified?
Sols are classified on the basis of size of solid particles present in it. Explanation: When solid particles that are very small in size are present in a continuous liquid medium then the solution formed is known as sol. For example, blood, cell fluid, milk of magnesia etc are all sols.
Which is Lyophobic in nature?
Sols of inorganic substances like sulphur are lyophobic.
What does Lyophobic mean?
Medical Definition of lyophobic
: marked by lack of strong affinity between a dispersed phase and the liquid in which it is dispersed — compare lyophilic, hydrophobic sense 3, oleophobic.
Why Lyophobic sols are irreversible?
In Lyophobic sol, weak forces of interaction exist between colloidal particles and liquid. ... Unlike Lyophilic colloids, the precipitations of lyophobic colloids do not regain their original state as coagulated mass cannot be dispersed into colloidal form. This shows that lyophobic sols are also irreversible in nature.
What is Lyophilic and Lyophobic solution?
In lyophilic sols, the dispersed phase particles have great affinity (or love) for the dispersion medium. These sols are reversible. Examples include gum, gelatin, starch, proteins and rubber etc. In lyophobic sols, the dispersed phase particles have no affinity (or love) for the dispersion medium.
What is difference between solution and colloid?
True solutions are the mixtures in which the solute and the solvent mix properly in the liquid phase. 1. Colloidal solutions are the mixtures in which the solute is uniformly distributed in the solvent.
