which one of the following is an example of lyophilic sol?
530324
If 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 forms lyophilic sol when water is used as the dispersion medium.

The species (atoms or molecules) constituting the dispersed particles in multimolecular colloids are held together by Vander Waals' forces. The gold sol, sulphur sol etc. are some examples of multimolecular colloids.

However addition of very large quantities of electrolytes can cause particles to precipitate. If large quantity of liquid is added to precipitations or the colloidal solution is stirred properly lyophilic sols can regain their original state. This shows that lyophilic sols are also reversible in nature.

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. ... Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane.

The most common examples of such compounds are soaps and detergents, four of which are shown below. Note that each of these molecules has a nonpolar hydrocarbon chain, the "tail", and a polar (often ionic) "head group". ... Soap is manufactured by the base-catalyzed hydrolysis (saponification) of animal fat.

The key difference between sol solution and suspension is that the particles in a sol have dimensions around 1 nanometer to 1 micrometre and a solution has particles with dimensions below 1 nanometer whereas a suspension has particles with dimensions higher than 1 micrometre.

Hydrophobic is often used interchangeably with "oily" or lipophilic". Examples of hydrophobic molecules include the alkanes, oils, fats and greasy substances in general.

Solution is clear, particle size is less than 1 nm, solute is completely soluble in solvent. ... Particles insoluble in solvent. Large paticle size. Sol is a type of colloid inn which dispersed phase is solid and dispersion media is liquid.

Lyophilization and freeze drying are terms that are used interchangeably depending on the industry and location where the drying is taking place. Controlled freeze drying keeps the product temperature low enough during the process to avoid changes in the dried product appearance and characteristics.

Examples of active ingredients used in Lysol products: ethanol/SD Alcohol, 40 1–3%; fluid that acts as sanitizer. isopropyl alcohol, 1–2%; partly responsible for Lysol's strong odor; acts as sanitizing agent and removes odor. p-Chloro-o-benzylphenol, 5–6%; antiseptic.

Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. The hydroxyl group is referred to as a hydrophilic (“water-loving”) group, because it forms hydrogen bonds with water and enhances the solubility of an alcohol in water.

Ampholytes are most lipophilic and least soluble in their neutral form. However, zwitterions are always charged; they are rarely lipophilic, and they are often soluble in water at any pH.

Molecules such as proteins, nucleic acids, and carbohydrates have an affinity for water and are called hydrophilic (“water-loving”). Lipids, however, are hydrophobic (“water-fearing”). Some lipids are amphipathic—part of their structure is hydrophilic and another part, usually a larger section, is hydrophobic.

The polar head is hydrophilic and the nonpolar tails are hydrophobic. When added to water, phospholipids for spheres, called micelles. ... They are hydrophobic molecules with a firm, pliable consistency. This property makes them ideally suited to form waterproof coatings on various plant and animal parts.

Example of cationic detergents are quaternary ammonium compounds, benzalkonium chloride and cetyltrimethyl ammonium bromide. They will precipitate when mixed with an anionic detergent (soap).
