A mixture is a combination of two or more components that are not chemically linked.There are two sorts of mixtures: homogeneous mixtures and heterogeneous mixtures. A homogenous mixture is one whose composition is consistent throughout. It is the sort of mixture in which the composition remains consistent throughout or where the components of the mixture are spread equally.Recommended: Study for your Exams with Safalta School online.

Suspensions
Solutions
Salt or sugar dissolved in water is an example of a solution. The particles are less than 2 x 10-9 m in size. They are so small that you cannot distinguish between the solute (the thing being dissolved) and the solvent (the thing that dissolves the solute).
Colloids
Colloids are the ones whose particle sizes range from 2 x 10-9 m to 5 x 10-7 m. Here the particles are small enough that they remain suspended. The intermolecular forces are strong enough to overcome the nature of particles to settle or float, owing to their small sizes. A few examples are given below which will help you better understand the nature of colloids.
Colloids are classified as follows:
Colloids can be further catcategorized on their dispersion medium (solid, liquid, or gas). Here is a table to assist you.
Phase of Dispersion | Medium of Dispersion | Colloid Type | Example |
Solid | Solid | Solid Sol | Gemstones, Pearls |
Liquid | Solid | Gel | Cheese, Jellies, Jam |
Gas | Solid | Solid Sol | Pumice Stone |
Solid | Liquid | Sols | Gum, Cell Fluids |
Liquid | Liquid | Emulsion | Milk |
Gas | Liquid | Foam | Froth, Whipped Cream |
Solid | Gas | Aerosol | Smoke |
Liquid | Gas | Aerosol | Fog, Clouds |
