aration Techniques Classification of Matter
nigerianscholars //separationtechniques CachedPaper Chromatography. This method is often used in the food industry. It is used to identify chemicals (coloring agents) in foods or inks. For example, if a scientist wants to know how many substances are in a particular blob of ink, paper chromatography can be used. Filtration. This is a more common method of separating an insoluble solid from a liquid. An example of such a mixture is sand and water. Filtration is used in water treatment plants, where water from rivers is filtered to remove solid particles. Evaporation. Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent. The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue. Simple Distillation. Distillation is the process of separating the components or substances from a liquid mixture by selective boiling and condensation. Chat
