What is the difference between Lyophilic and Lyophobic?
All particles in a lyophobic sol have the same charge. Particles in the lyophilic sol absorb H+ and OH- ions from the medium. Particles in a lyophobic sol absorb ions from the medium. Particles in a lyophilic sol may or may not migrate towards the electrode.
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 Lyophilic 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 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.
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.
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 are Lyophobic colloids give an example for them?
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.
What is a lyophobic colloid?
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.
Is lyophobic colloid more stable than Lyophilic?
The stability of lyophilic sols is a result of two factors, the presence of a charge and the solvation of colloidal particles. On the other hand, the stability of lyophobic sols is only because of the presence of a charge. Thus, the lyophilic sol is more stable than lyophobic sol due to the extensive solvation.
Is starch a lyophobic colloid?
Gelatin, starch and gum all are examples of lyophilic colloids and sulphur is an example of lyophobic colloids.
Is starch in water a lyophobic colloid?
Only starch in water is a lyophobic colloid because it has no affinity for liquid.
