Colloidal Dispersions – Summary

Unit I introduces the concept of colloidal dispersions, which are heterogeneous systems consisting of particles dispersed in a continuous medium. The unit begins with the classification of dispersed systems, such as true solutions, colloidal dispersions, and suspensions, based on particle size and behavior.

Further, it elaborates on the general characteristics of colloidal systems, including the size and shape of colloidal particles, typically ranging from 1 to 1000 nanometers. The unit classifies colloids into lyophilic and lyophobic types and also based on the physical state of dispersed and dispersion phases (sols, gels, emulsions, aerosols, etc.).

Key properties of colloids are discussed, such as optical properties (Tyndall effect), kinetic properties (Brownian motion, diffusion), and electrical properties (electrophoresis, electro-osmosis, zeta potential). These properties help distinguish colloidal systems from true solutions and suspensions.

Moreover, the unit explores the effect of electrolytes on colloidal stability, including coacervation (aggregation of colloidal particles), peptization (conversion of a precipitate into a colloid), and the protective action of lyophilic colloids in preventing the coagulation of lyophobic colloids.

Overall, this unit builds a strong foundation in understanding colloidal behavior and their critical role in pharmaceutical and industrial applications.

This unit provides a comprehensive understanding of stereochemistry, vital for advanced studies in medicinal and pharmaceutical chemistry.
