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 a result, the particles come […]
Colloidal particles exhibit diverse sizes and shapes, ranging from nanoparticles to microparticles with spherical, elongated, or irregular geometries. Understanding the size and shapes of colloidal particles is crucial for designing and tailoring their properties for specific applications in fields such as nanotechnology, materials science, and biomedicine. Classification of Colloids Colloids are heterogeneous mixtures composed of […]
