Seperation+Techniques

Separation Techniques There are many kinds of separation techniques. They are: · Magnetic attraction · Filtration · Evaporation to dryness · Distillation · Chromatography · Sublimation · Separating Funnel Magnetic Attraction This process is used to separate magnetic objects from non-magnetic objects in a mixture. Example: Electromagnets are used to remove steel and iron at the junk-yard. Filtration This process is used to separate insoluble solids from the liquid in a solid-liquid mixture. The insoluble solid that remains on the filter paper is called residue. The liquid that passes through is called the filtrate. Example: Air filters used in air conditioners Evaporation to Dryness Evaporation to dryness is a process used to separate a dissolved solid that does not decompose on heating from a solution. Example: Drying hair with a hair dryer Distillation Distillation is a process used to separate a liquid from a solid-liquid solution or liquid-liquid solution. Example: Pure water can be distilled from soft drinks Fractional Distillation This process can be used to separate miscible liquids with different boiling points where the liquid with the lower boiling point will vaporize first. Example: Alcohol and water can be separated with this method Chromatography Chromatography is a process used to separate the different components in a liquid or gaseous mixture. Example: Separate the different colored components that make up black ink Using Separating Funnel A separating funnel can be used to separate two immiscible liquids. Example: Separate oil and water Sublimation This method is used to separate a solid which sublimes when heated. Example: Separate mixture of ammonium chloride and sodium chloride With that, I have come to the end of explaining separation techniques. Reflections After learning about the different seperation techniques, I know what to do when I accidentally mixed up some stuff and need to seperate them both again. It is also very useful to know about how to seperate different substances as you may use it one day and you will never know it. It might just come in handy.
