There are six ways to separate mixtures including sedimentation, decantation, filtration, evaporation, crystallization and distillation. Mixtures are made up of both solids and liquids.Continue Reading
Mixtures that contain only solids must be separated through sublimation, extraction, magnetic separation or chromatography. Mixtures that contain only liquids must be separated through fractional distillation or gravity separation.
Sedimentation is the process of separating the insoluble solid from the liquid by allowing the solid to settle at the bottom of the container. Decantation is similar to sedimentation, but it also involves pouring off the liquid in order to leave the solid behind. Filtration is used to separate by pouring the liquid and solid through a funnel into a container where the solid is retained by the filter.
Evaporation is a method that involves evaporating the solvent in the mixture. An example of this is a salt and water mixture where the water can be evaporated in order to leave the salt behind. Another example of this would be copper sulphate, potash alum, sugar and potassium nitrate. Crystallization is an evaporating technique that works to form crystals of the solute and then dissolve those crystals out of the solution. Distillation is a process of heating a solution that contains soluble solids to form vapors of the liquids and then cooling the vapors once again to get the liquid back, but without the solid.Learn more about Solutions & Mixtures
It is not recommended to distill a solution to dryness because the residue left in the distillation flask can cause an ignition or an explosion. A similar consequence can occur if joints of the apparatus are not tightly secured.Full Answer >
To separate alcohol from water, you must heat the solution, evaporate the ethanol into vapor, cool it down and condense it back into a liquid using a distillation apparatus. This process is called distillation, and it is used to separate a pure liquid from a liquid mixture. Distillation works for liquids that have different boiling points.Full Answer >
The most common methods of removing salt from water are distillation and reverse osmosis. Distillation refers to the process of purifying water through evaporation and condensation, while reverse osmosis uses a semi-permeable membrane to remove salt and other particles from water.Full Answer >
According to the American Fuel and Petrochemical Manufacturers, diesel fuel is refined from crude oil through the use of a distillation column, making use of the varying boiling points of all the various chemicals in crude oil to separate products from the crude oil mixture. Diesel fuel is then further refined to remove pollutants in order to achieve the cleaner-burning low-sulphur diesel used commercially.Full Answer >
