Chemistry Solutions Solutions. Simon Moore. Jul 10, A colloid is a suspension, but a specific type. Explanation: A colloid is a suspension, but specifically colloids have a dispersed phase where the mean particle size is between 1 and nm, and also they are sufficiently stable that they do not separate upon standing to any observable extent.
Related questions How are solution, solute, and solvent related? Why do solutions become saturated? How does temperature affect solutions? The particles don't settle down when the colloid is left undisturbed. Seperation Suspension is unstable. The components can be separated from the mixture by the process. The components cannot be separated from the mixture by the process of filtration or decantation. The centrifugation technique is used in separation. Like Dislike Related Differences.
The particles of suspensions scatter a beam of light passing through it and make its path visible. The solute particles settle down when a suspension is kept is undisturbed. Email required.

They form: Dispersed phase — the dispersed substance; Continuous medium — the substance in which the dispersed phase is distributed.
Depending on the size of the particles of the disperse phase there are: Heterogenous rough dispersion systems — the particles are bigger than nm: Suspension — a liquid and solid component; Emulsion — two liquid components; Aerosol — the dispersion medium is a gas. What is Colloid? Depending on how the particles of the dispersed phase refer to the medium, the colloid systems are: Lyophilic — adsorb a large number of molecules from the dispersion medium gelatin, soaps, Fe OH 3 , Al OH 3 ; Lyophobic — do not bind or bind with a small number of molecules from the dispersion medium salts of certain metals, poorly soluble metal sulphides, etc.
Depending on the colloid particle structure the colloid systems are subdivided into: Associated micellar — the particles are groups of atoms, ions or molecules e.
Depending on the nature of the medium, the colloids are: Hydrosols — the solvent is water; Benzenosols — the solvent is benzene; Etherosols — the solvent is ether etc. Dispersion methods — dispersion of the material to the size of the colloidal particles in the presence of a dispersion medium; Condensation methods — condensing grouping individual molecules, atoms or ions into particles of colloid size.
What is Suspension? The classification of the suspensions is based on the dispersed phase and the dispersion medium. The suspensions are obtained by various dispersion and condensation methods. Difference Between Colloid and Suspension Definition Colloid: Dispersion system with a liquid and solid component, with particles size between 1 and nm is called colloid.
Particle size Colloid: The particle size is nm. Suspension: The particle size is above nm. Particle visibility Colloid: The particles in the colloid cannot be seen with a naked eye. Suspension: The particles in the suspension can be seen with a naked eye. Suspension: The suspensions undergo sedimentation.
Homogeneity Colloid: The colloids are relatively homogenous. Suspension: The suspensions are heterogeneous. Permeability through filter paper Colloid: The colloid particles can pass through filter paper. Suspension: The suspension particles cannot pass through filter paper.
