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 Lyophilic and lyophobic colloids explain with one example of each?

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 are the Lyophobic and Lyophilic colloids compare the two term with reference to stability and reversibility?

Compare the two in terms of stability and reversiblity. Answer : Solvent loving colloid is known as lyophilic colloid. They are stable and reversible where as solvent hating colloid is known as lyophobic colloid they are less stable irreversible.

What is Lyophobic and Lyophilic Sol?

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.

2) Dispersion phase has high affinity for dispersion medium.2) Dispersion phase has low affinity for dispersion medium.

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.

What are Lyophobic colloids give one example?

Lyophobic sols are those sols in which the particles of the dispersed phase have little affinity for the particles of the dispersion medium. Example: sols of metal and their sulphides and hydroxides.

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 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.
