Main Types of ColloidsMultimolecular Colloids - Consist of aggregates of atoms or small molecules. Example: sulfur sol.Macromolecular Colloids - Contain large macromolecules dispersed in a medium. Example: starch, proteins.Associated Colloids - Form micelles at certain concentrations, acting like colloids. Example: soaps and detergents.Colloids can also be classified based on the physical state of the dispersed phase and dispersion medium into types like sols, gels, foams, aerosols, emulsions, and solid sols.Additionally, based on affinity with the medium:Lyophilic Colloids (solvent-loving, stable) Example: gelatin.Lyophobic Colloids (solvent-hating, unstable) Example: gold sol.
