Effect of Electrolytes: 1. Coagulation or Precipitation: Addition of electrolytes to colloidal dispersions can lead to coagulation or precipitation of the colloidal particles. This occurs due to the neutralization of surface charges on the colloidal particles by oppositely charged ions from the electrolyte, reducing the electrostatic repulsion between particles. As …

Colloidal Dispersions: Classification and General Characteristics
1. Introduction to Colloidal Dispersions: Colloidal dispersions, also known as colloids, are heterogeneous mixtures in which one substance is finely dispersed in another. The dispersed phase consists of particles with dimensions ranging from 1 to 1000 nanometers, typically suspended in a continuous medium, known as the dispersion medium. Colloids …
