Answer 2

Answer:

Explanation:

→ Colloids in which the dispersed particles display an affinity for the dispersant medium are referred to as lyophilic, whereas those that repel the dispersant are referred to as lyophobic. Lyophobic colloids are characterized by the absence of bonds between the dispersed phase and the dispersant. When the dispersant is water, these colloids are referred to as hydrophilic or hydrophobic, respectively.

→ Hydrophilic colloids absorb water, swell, and can give rise to a special type of colloid known as a gel. Here, the liquid appears to be completely absorbed into the dispersed phase. A gel has the appearance of a solid and is elastic and gelatinous, as seen in the classic example of this type of substance, namely gelatin. These colloids are generally made up of macromolecules dispersed in water.

→ Hydrophobic colloids are formed by the aggregation of spatially ordered particles and are referred to as microcrystals.
