In a colloid, the particles are not fully dissolved but are evenly distributed throughout the mixture, giving it a uniform appearance. An example of a colloid at home is milk, which is a mixture of fat molecules dispersed in water. Suspensions may scatter light, but if the number of suspended particles is sufficiently large, the suspension may simply be opaque, and the light scattering will not occur. Colloids are found to be useful in daily use and industrial applications. Another way to define colloids and segregate them are: Sol– It is a colloidal system where solid particles are the dispersed phase in a liquid that acts as a dispersed medium.
