Mixtures are a physical combination of different substances. Since they are physically combined, they can also be separated physically. Below are some ways to separate components of mixtures:
1. Picking
This is used if the components of the mixture are big enough to be handpicked. This can be done to separate or segregate the components of the mixture. For instance, if you want to separate the different fruits in a fruit basket, picking is the most appropriate technique.
2. Winnowing
This technique of separating the components of the mixture is carried out with the help of wind or blowing air. An example of a mixture that can be separated by winnowing is when we separate the husk and chaff of rice.
3. Sieving
This technique is used separate mixtures that contain substances that are of different sizes. The mixture is allowed to pass through the pores of the sieve wherein the smaller substances pass through and bigger components of the mixture are retained.
4. Evaporation
This technique is used to separate a solution, which is made of solvent and soluble solid. In this technique, the solution is heated until the liquid solvent evaporates and is changed to gas. As the solvent evaporates, the solid residue or solute is left.
5. Sedimentation
This technique is used if the mixture is made of insoluble solid and liquid. In this technique, the mixture is left undisturbed to allow the insoluble solid to settle at the bottom of the mixture.
6. Filtration
This technique is used if the mixture is made of insoluble solid and liquid. It makes use of a filter. The mixture is poured, allowing the filtrate or liquid to pass through, leaving the insoluble solid in the filter.
7. Decantation
This technique is used in mixture made up of immiscible liquids or suspension. In this technique, the mixture is slowly pouring out the less dense substance leaving behind the denser material.
8. Use of Magnet
This technique is used when one substance in the mixture has magnetic properties. The magnet attracts magnetic materials leaving behind the non-magnetic materials.
