Seperation Methods
Distillation:
Simple Distillation:
is a technique for separating a solution's solvent. Simple distillation, for example, can extract water from a salt solution. Because water has a lower boiling point than salt, this approach works. The water evaporates as the solution is heated. After that, it's chilled and condensed into its own container. Because the salt does not evaporate, it remains.
Fractional Distillation:
is a liquid separation technique that involves separating a liquid from a combination of two or more liquids. Fractional distillation, for example, can separate liquid ethanol from a mixture of ethanol and water. Because the liquids in the mixture have different boiling points, this approach works. One liquid evaporates before the other when the mixture is heated.
Filteration
Is a separation method for an insoluble solid from a liquid. When a sand and water mixture is filtered:
In the filter paper, the sand remains (it becomes the residue)
-
Evaporation:
A soluble solid is separated from a liquid using this device. Copper sulfate, for example, is soluble in water and forms a copper sulfate solution when its crystals dissolve in it. The water evaporates during evaporation, leaving behind solid copper sulfate crystals.
Chromatography
A method for separating dissolved components from one another is paper chromatography. When dissolved substances are colored, such as inks, food colorings, and plant dyes, it is frequently utilized. It works because certain of the colored compounds dissolve in the solvent used more quickly than others, allowing them to travel up the paper further.
Mechanical
Sorting is the easiest approach to separate mechanical mixes. When two (or more) types of materials are in relatively big chunks, sorting is used. Sorting is as simple as looking at the different pieces and physically shifting one or more of them to a different container.
Magnetic
is a method of separating components of mixes by attracting magnetic objects with magnets. The magnetic separation method separates non-magnetic materials from those that are magnetic. Gold, silver, and aluminum are examples of non-magnetic metals. Examples of magnetic metals are iron, nickel, steel etc.
