Colloidal Sols

Colloidal sols are mixtures where tiny particles are suspended evenly throughout a fluid, such as water or air. These particles are larger than molecules but small enough to remain dispersed without settling out quickly. The particles can be solid, liquid, or gas, and their small size gives the mixture unique properties, like being cloudy or translucent. Examples include milk (fat particles in water), gelatin, and smoke. Colloidal sols are stable because the small particles stay suspended due to Brownian motion, preventing separation over time. They are important in various industrial, medical, and environmental applications.
