WebThe intensity of Tyndall scattering increases with increase in the size of colloidal particles as well as the concentration. Starch sol is a lyophilic sol. Hence the sol particles are very small and highly solvated. There is almost no difference in the refractive indices of dispersion medium (water) and dispersed phase (starch). WebSuch kinds of sols are known as lyophobic sols. These kinds of colloidal solutions always carry some charge on them. All the particles of a given colloidal system have like charges because of which they don’t combine together and settle down. This is the main cause of the stability of colloids. WebIf water is used as the dispersion medium, lyophilic sols are called hydrophilic sols. Starch, gum, gelatin, egg albumin etc. are examples of lyophilic sols. Starch Sol.

WebExample : Gold sol, sulphur sol. What is association colloid? ... When a lyophilic sol is added to the lyophobic sol, the lyophilic particles form a layer around lyophobic particles and thus protect the latter from electrolytes. Lyophilic colloids used for this purpose are called protective colloids. WebExamples of lyophilic sols Starch sol: When water is the dispersion medium, starch produces lyophilic sol; its preparation involves heating the starch sol and water to 100°C. Heating accelerates the creation of sol. It is highly stable and is unaffected by the presence of electrolytic impurities.

WebThe special feature of lyophilic colloids are that they are stable by itself due to stabilising interactions between the dispersed phase and dispersion medium. The sol can be retrieved by blending with the medium of dispersion again (for example, via evaporation). Also known as reversible sols, these sols may be used in both directions. WebSome examples of negatively charged sols are starch and arsenious sulphide. Positively charged sol of hydrated ferric oxide is formed when FeCl 3 is added to excess of hot water and a negatively charged sol of hydrated ferric oxide is formed when ferric chloride is added to NaOH solution. The lyophilic sols are directly formed by mixing

Web(i) Lyophilic sols (solvent loving): They are those in which the dispersed phase exhibits a definite affinity for the dispersion medium (liquid) or the solvent. For example: Dispersion … WebWhat is Lyophilic sol? What are Lyophilic Sols? Lyophilic means ‘liquid loving’.

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, …

WebThe sol can be converted to gel by cooling. The gel can be converted to sol by heating. 5: The sol can be easily dehydrated. The gel cannot be dehydrated. 6: The viscosity of the sol is very low. The viscosity of the gel is very high. 7: Sol is categorized into lyophobic and lyophilic sols. There is no such classification of gel. 8: Example: Blood

WebPreparation: A lyophilic sol can be prepared by the direct addition of the dispersion phase (colloids) into dispersion medium (liquid). Examples: Starch, gums, proteins, soaps, and metasilicic acids are some examples. Colloids can be either lyophilic or lyophobic.
