| SIEVING technique for separating particles of different sizes. Substances you can separate with it: flour, stones from sand, sugar. | Wikipedia contributors. (2020, 14 junio). Sieve. Recuperado 8 de julio de 2020, de https://en.wikipedia.org/wiki/Sieve#:%7E:text=Sieving%20is%20a%20simple%20technique,flour%20has%20very%20small%20holes.&text=Depending%20upon%20the%20types%20of,to%20separate%20stones%20from%20sand. |
| EVAPORATION technique used to separate out homogeneous mixtures where there is one or more dissolved salts. The method drives off the liquid components from the solid components. Substances you can separate with it: salt in water. | Libretexts. (2019, 16 octubre). 2.8: Methods for Separating Mixtures. Recuperado 8 de julio de 2020, de https://chem.libretexts.org/Bookshelves/Introductory_Chemistry/Book%3A_Introductory_Chemistry_(CK-12)/02%3A_Matter_and_Change/2.08%3A_Methods_for_Separating_Mixtures#:%7E:text=to%20one%20another.-,Evaporation,until%20no%20more%20liquid%20remains. |
| DISTILLATION process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Substances you can separate with it: salt from seawater, sugar from water, ethanol from water. | Wikipedia contributors. (2020b, junio 23). Distillation. Recuperado 8 de julio de 2020, de https://en.wikipedia.org/wiki/Distillation |
| DECANTATION process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. Substances you can separate with it: muddy water to clear water. | Wikipedia contributors. (2020a, mayo 15). Decantation. Recuperado 8 de julio de 2020, de https://en.wikipedia.org/wiki/Decantation |
| CRYSTALLIZATION separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. Substances you can separate with it: alum crystals from impure samples. | Wikipedia contributors. (2020b, junio 8). Crystallization. Recuperado 8 de julio de 2020, de https://en.wikipedia.org/wiki/Crystallization#:%7E:text=Crystallization%20is%20also%20a%20chemical,crystallization%20occurs%20in%20a%20crystallizer. |
| FILTRATION method for separating an insoluble solid from a liquid. Substances you can separate with it: mixture of sand from water. | Separating solids from liquids – filtration - Separating mixtures - KS3 Chemistry Revision. (s. f.). Recuperado 8 de julio de 2020, de https://www.bbc.co.uk/bitesize/guides/zgvc4wx/revision/1#:%7E:text=Filtration%20is%20a%20method%20for,paper%20(it%20becomes%20the%20filtrate%20) |
| MAGNETIC process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. Substances you can separate with it: magnetite and pyrrhotite from minerals. | Wikipedia contributors. (2020a, mayo 11). Magnetic separation. Recuperado 8 de julio de 2020, de https://en.wikipedia.org/wiki/Magnetic_separation#:%7E:text=Magnetic%20separation%20is%20the%20process,with%20those%20who%20are%20magnetic. |
| PAPER CHROMATOGRAPHY technique for separating dissolved chemical substances by taking advantage of their different rates of migration across sheets of paper. Substances you can separate with it: these are often coloured substances such as food colourings, inks, dyes or plant pigments. | paper chromatography | Definition, Method, & Uses. (2020, 18 mayo). Recuperado 8 de julio de 2020, de https://www.britannica.com/science/paper-chromatography#:%7E:text=Paper%20chromatography%2C%20in%20analytical%20chemistry,very%20small%20quantities%20of%20material. |
| CENTRIFUGATION technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. at from milk to form skimmed milk. To remove solid components from blood in research labs. Substances you can separate with it: to separate water from clothes by spin drying in washing machines. | Centrifugation Theory. (s. f.). Recuperado 8 de julio de 2020, de https://www.fishersci.se/se/en/scientific-products/centrifuge-guide/centrifugation-theory.html#:%7E:text=Centrifugation%20is%20a%20technique%20used,spun%20at%20a%20define%20speed. |
