What is the difference between Lyophilic colloid and lyophobic colloid?
Lyophilic colloids or lyophilic sols – solvent-loving. In case of water as a dispersion medium, they are known as hydrophilic….Difference between Lyophilic and Lyophobic Colloids.
| Lyophilic Colloids | Lyophobic Colloids |
|---|---|
| Highly solvated, dispersed particles are covered by a layer of dispersion medium | Dispersed particles are not solvated |
What is the difference between lyophobic sols and Lyophilic sols?
Hint: Sols are basically colloidal mixtures where the dispersed phase is a solid and the dispersion medium is a liquid….Complete step by step answer:
| Lyophilic sol | Lyophobic sol |
|---|---|
| The stability of Lyophilic sols is higher than lyophobic sols | The stability of lyophobic sols is lesser than lyophilic sols. |
What do you mean by Lyophilic and lyophobic colloidal solutions?
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 are Lyophilic and lyophobic colloids which of these sols?
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 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.
What is the cause of stability of lyophobic sols?
(i) Lyophilic sols are stabilized due to a layer of solvent around sol particles. (ii) Lyophobic sols are stabilised due to presence of charge.
What is the difference between Lyophobic sol and Lyophilic sol?( Any two points?
They are solvent hating sols. In lyophobic sols, the dispersed phase does not have any attraction for the dispersion medium….Difference between Lyophilic and Lyophobic Sols.
| Sl. No. | Lyophilic Sol | Lyophobic Sol |
|---|---|---|
| 8 | Lyophilic sols are much stable than lyophobic sols. | Lyophobic sols are comparatively less stable. |
What is difference between solution and colloid?
Main Difference – Colloid vs Solution The main difference between colloid and solution is the size of their particles. Particles in solutions are tinier than that of colloids. Solute particles are not visible under a light microscope; however, colloid particles can be seen under the same.
What is the difference between a colloidal solution and an emulsion give one example of each?
A colloid is a substance in which microscopic particles are dispersed in a medium, but are not dissolved in it. Pumice could be an example of a colloid: particles of air dispersed in solid stone. An emulsion is a particular type of colloid, referring to microscopic particles of liquid dispersed in another liquid.
Why are Lyophilic sols more stable than Lyophobic sols?
The lyophilic sols are more stable than lyophobic sols because lyophilic sols are solvent loving whereas lyophobic sols are solvent hating. Lyophobic sols are more stable because the colloidal particles are more solvated. Therefore, option C is the correct option.
Are Lyophobic sols highly stabilized?
What is a Lyophobic solution?
Lyophobic means ‘liquid-hating’. That means in these solutions there is little or no interaction between the dispersed phase and the dispersion medium i.e. dispersed phase has little affinity for dispersed medium. These solutions are easily precipitated by the addition of small amounts of electrolyte, by heating.
