As we’ve outlined in recent blogs, homogenization is a procedure utilized for fragment size reduction and works by use mechanical pressure to breakdown particles or droplets in a liquid into smaller and much more uniform sizes. The result of homogenization is a dispersion, inside fine particles of one substance space scattered throughout one more substance. Furthermore, dispersions room able to be classified by the sizes of this scattered particles: solutions, suspensions and colloids. In this blog, we’re focusing on the difference between suspension and colloids.

You are watching: Compare and contrast solutions and suspensions


Simply characterized as a heterogeneous mixture of 2 substances in which one is dispersed into the other, suspensions involve particles bigger than those discovered in solutions, commonly over 1,000 nm. The bigger corpuscle of a suspension usually work out or different out that a mixture upon standing or room able to it is in filtered out, return not through filter paper. Heaviness is able to traction the clearly shows particles in a suspension under if undisturbed, and also they will remain that means unless being actively mixed. Examples of suspensions include oil and also water, dust or soot in air, sand and also water and muddy water.


Although a heterogeneous mixture of 2 substances prefer suspensions, colloids involve particles from 1-1,000 nm that do not different upon standing and also cannot it is in separated by filtration. The corpuscle in a colloid floor in size between those in a solution and a suspension and may it is in solid, fluid or gas. The two parts in every colloid mixture room its particles and also the dispersing medium, and the particles room spread evenly in in the medium, i m sorry can also be solid, fluid or gas. Instances of colloids space foams (shaving cream, Styrofoam), gels (gelatin, jelly), emulsions (mayonnaise, lotion), aerosols (fog, insecticide spray, smoke) and also sols (shampoo, gemstones).

Even though the corpuscle in a colloid room very tiny in size, they can be seen through a process called the Tyndall Effect, the result of irradiate scattering in colloidal dispersion while showing no irradiate in a true solution. This effect is used to identify whether a mixture is a true solution or a colloid.

Colloid mills, prefer homogenizers,are able to procedure particle palliation formulations, although each is preferential for details applications.They are best used because that samples comprised of solids immersed in a fluid suspension or a fluid suspended in one more liquid due to the fact that they can enhance the stability and/or minimize the size of rely particles.

In summary, complying with are some of the key differences between a suspension and colloid:

Particles in a suspension room usually more than 1,000 nm, if those in a colloid range from 1-1,000 nm.Unlike those in a suspension, corpuscle in a colloid carry out not separate once sitting still. The particles in a suspension might be be separate by filtration uneven those in a colloid.Colloids are able come scatter light, however suspensions can not transmit light.Particles in a suspension have the right to be seen by the nude eye, yet those in a colloid have to be viewed using a irradiate microscope.
