Which is the type of separation technique being demonstrated in the figure?

Answer 1

There is distillation, evaporation, chromatography, using of separating funnel, centrifuging, desalination, fractional distillation, crystallization, fractional crystallization, decanting, filtration, sublimation and fractional sublimation. Decanting is the process where it is used to separate the liquid from the denser solid(s) by simply pouring the liquid out from the beaker. Filtration is the process where a filter paper and funnel is used. It is used to separate the liquid from the solid(s), mostly suspensions. The residue is then collected on the filter paper. A separating funnel is used when there are two liquids and one is denser than the other. The denser liquid will sink, thus an outlet at the bottom is opened for the denser liquid to flow out. When the denser liquid is drained, the outlet is shut. The cap of the funnel is then open for the less dense liquid to be poured out. Crystallization is a process where a thermally unstable mixture is heated till about a third of the solvent is left to obtain the crystals, or it will decompose. Evaporation is where a thermally stable is heated till dryness to obtain the crystals. Chromatography is the use of a chromatography paper and dyes. This is to separate the dyes from each other, based on their solubility in water. They can also be used in a police case, where evidences such as ink and dyes are compared to see which matches, food dyes and the patient's urine for medical purposes. Desalination is the process of separating water from sea water through evaporation and condensation. Distillation is the evaporation and condensation of a water from a mixture. This can be used to obtain distilled mineral water. Fractional distillation is the process where the mixture is separated by differences in their boiling points. The substance with the lower boiling point will reach the top of the fractionating column first, where it is then condensed. Centrifuging is used to separate the solid(s) from the liquid. The mixture spun very fast around the centrifuge tube in the centre of the beaker. The solid(s) will then be forced into the tube. Sublimation is the process where a solid is immediately turned to gas. The gas will then be condensed. This method is used when separating two solids. This is when one solid sublimes while the other does not.
