Colloidal solutions are heterogeneous mixture of two or more substances.General Characteristics of Colloidal Solution: are some common examples of colloidal solution. Milk, ink, blood, solution of soap or detergent, etc. Colloids cannot be separated by filtration but can be separated using centrifugation. Particles of colloidal solution are not visible through naked eye but scatter the ray of light, i.e. Colloids are dispersed throughout the solvent. Particles of colloidal solution are called colloid. Colloidal solutions appear homogenous because of relatively small size of particles in comparison with suspension. are some examples of suspension.Ĭolloidal solution is a heterogeneous mixture of two or more substances. Milk of magnesia, fog, mixture of chalk and water, etc.Suspension does not scatter light when particles are settled because in this case suspension breaks.The particles of suspension can be separated through the process of filtration.When suspension is left for some time, particles get settled in bottom.Suspension shows Tyndall effect because of their large size of particles.They are greater than 1 nanometre (`10^(-9)` metre). The size of particles of suspension is large enough to be visible from naked eyes.Particles of solute do not dissolve in solvent rather they remain suspended in bulk throughout.Suspensions are heterogeneous mixture of two or more substances.
