Separating Mixtures (Grade 6) power point
- 1. Separating Mixtures MR. TROY JOHNREI M. BAUTISTA
- 4. Separating Mixtures A mixtureis composed of two or more types of matter that can be present in varying amounts. It can be physically separated by using methods that use physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.
- 5. Filtration Some heterogeneous mixtureswith large solids can be separated using strainers But some particles of suspensions are too small to be strained fine suspended particles are instead filtered using filter paper
- 6. • Filter paperhas finer holes for water to pass through but not ground coffee • Filtrate - liquid that passed the filter • Residue - insoluble large molecules that are left behind
- 9. Sedimentation and Decantation. Sedimentation isa process that allows the sediments (solid particles) to settle at the bottom of a container.
- 10. Decantation • Decantation ispouring or scooping the topmost liquid. • The process can be carried out by tilting the mixture after pouring out the top layer. • Immiscible liquids- liquids that do not mix (e.g. oil and water) • Separating immiscible liquids is not simple in large scale situations just like oil spills • Some use ships with pumps to suction out the oil
- 11. Sieving • Separation using strainers •Separating components of a mixture by sizes
- 12. Sedimentation, decantation, and filtration areuseful separating techniques such as in water purification. to purify water, suspended particles are filtered out while substances that is heavier than water are made to settle out through sedimentation and removed through decantation.
- 13. Evaporation • The methodused to separate salt from seawater • Evaporation is when liquid becomes gas because of heat • Evaporation can be used to purify water • Water evaporates, leaving the impurities behind • Water vapor then condensed back into being pure liquid water
- 15. Distillation • It isused in homogeneous mixtures whose components have a big difference in boiling points. • Distillation is important in the petroleum and wine industries.
- 16. Crude Petroleum • Itis distilled to obtain different products such as gasoline, diesel, fuel, kerosine, oil, and other petroleum products.
- 17. Alcoholic Beverages Different kinds of alcoholic drinksare made from wine through distillation.

- 21. Magnetism Components ofsolid mixtures can also be separated through magnetism. This process is commonly used in mining where magnetic materials such as iron are extracted from the soil. Landfills and junkyards use strong magnets to segregate metallic objects from other materials.
- 22. Crystallization is theprocess by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas. E.g. Making rock salt from seawater and rock candies, such as lollipops. Complete evaporation of water results to the formation of crystallization.
- 23. Sublimation Is usedto separate components of a solid mixture. One components to separated in this mixture will turn into gas.
- 24.
- 25.
- 26. Chromatography Separates thedifferent components of a mixture using an absorbent material. The most common form of chromatography is paper chromatography.
- 27.
- 28. It’s recap time!! Mixtures may be separated through physical means. The common separation procedures are filtration, sedimentation, decantation, and distillation. Special techniques such as magnetic separation, crystallization, sublimation, and chromatography are also employed in different laboratories and industries.
