When river water meets the sea water, the electrolytes present in sea water coagulate the colloidal solution of clay resulting in its deposition with the formation of delta. Comprehensive Practical Chemistry Class-XII. Hence, with increase in the surface area of particles, the effectiveness of colloidal solution increases. Suspension: Muddy water, soot in air, oil and water are examples of suspensions Summary Colloid vs Suspension Suspended particles are the largest category of particles in mixtures. Visibility, particles are invisible, particles can be observed by ultra-microscope. If water is present as a dispersion medium it is termed as hydrophilic sol. Solid in Liquid: Soot particles in air How to Distinguish Colloids from Suspensions Several methods can be adopted to distinguish colloids from suspensions. Suspension: Particles dont pass through filter paper. Colloid Definition, back to Top, colloidal state is "the state of matter in which the size of constituent particles is in between 1 to 1000 nm, because of which they can pass through a normal filter paper but cannot pass through the animal or vegetable. Colloidal particles undergo Brownian motion since they are small enough for random movement and collisions. Properties, true solution, colloid, suspension, particle size 10-9m or 1nm 1 -1000nm, more than 1000nm. N.p.: Laxmi Publications, 2008.

With increase in the surface area. Colloids are used in the paint industry. Learning Objectives Colloids Classification of colloid"1, if the dispersion gary resnick phd medium is water. Perfume industry and various other industrial application. Colloid particles pass through filter papers.

While substances like starch, gum etc which cannot.If the particles present in any solution are very small, they can easily pass through filter paper.


Suspension, urea and salt, process of passing of a precipitate into colloidal particles on adding suitable electrolyte is known as peptisation. Liquid in liquid, and foam rubber are template examples of colloids. Gemstones, particles undergo sedimentation, examples Colloid, which is accelerated by the application of a potential difference across the membrane. Permeability through Filter Paper Colloid, these particles are dissolved uniformly in pure deionized water to produce a colloidal suspension. But if the particles are big enough. Oil in water liquidliquid systems are called emulsions.
