Описание: Types of colloidal systems | Lyophillic colloids | solvent loving colloids | lyophillic in English

This video explains the types of colloidal systems, with a focused discussion on lyophilic colloids, their properties, classification, and examples. It clearly distinguishes between lyophilic, lyophobic, and association colloids and explains why lyophilic colloids show strong interaction with the dispersion medium.
The concept of solvation and the subdivision of lyophilic colloids into hydrophilic and lipophilic systems are also explained in a clear, exam-oriented manner.

This video is especially useful for pharmacy, chemistry, medical, and life-science students studying physical pharmacy and colloidal systems.

⏱️ Chapters & Key Concepts

00:04 – Types of Colloidal Systems
Introduces the three main types of colloidal systems: lyophilic, lyophobic, and association colloids.

00:09 – Lyophilic Colloids
Lyophilic colloids are solvent-loving systems in which the dispersed phase shows strong affinity toward the dispersion medium.

00:11 – Lyophobic Colloids
Lyophobic colloids are solvent-hating systems with weak interaction between the dispersed phase and the dispersion medium.

00:15 – Association Colloids
Association colloids exhibit properties of both lyophilic and lyophobic colloids.

01:02 – Affinity Between Dispersed Phase and Medium
In lyophilic colloids, dispersed particles readily interact and form bonds with solvent molecules.

02:01 – Solvation
Solvation is the process by which solvent molecules attach to dispersed particles, stabilizing the colloidal system.

02:10 – Types of Lyophilic Colloids
Lyophilic colloids are further classified based on solvent affinity.

02:16 – Hydrophilic Colloids
Hydrophilic colloids have a strong affinity for water.

02:21 – Lipophilic Colloids
Lipophilic colloids have a strong affinity for oils or non-aqueous solvents.

📘 Key Definitions

Lyophilic Colloid
A lyophilic colloid is a solvent-loving colloidal system in which the dispersed phase has a strong affinity for the dispersion medium.

Lyophobic Colloid
A lyophobic colloid is a solvent-hating colloidal system with little or no attraction between the dispersed phase and the dispersion medium.

Association Colloid
An association colloid is a colloidal system that exhibits properties of both lyophilic and lyophobic colloids.

Solvation
Solvation is the process by which solvent molecules surround and attach to dispersed particles in a colloidal system, increasing stability.

Hydrophilic Colloid
A hydrophilic colloid is a lyophilic colloid that has a strong affinity for water.

Lipophilic Colloid
A lipophilic colloid is a lyophilic colloid that has a strong affinity for oils or non-aqueous solvents.
