Separation Techniques

There are many separation techniques, they are:

- Magnetic Attraction

- Filtration

- Evaporation to dryness

- Distillation

- Chromatography

- Using a separating funnel

Magnetic Attraction

This process is used to separate magnetic object

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.

Evaporation to dryness

Evaporatiion to dryness is a process used to separate a dissolved solid that does not decompose on heating from a solution

Distillation

Distillation is a process used to separate a liquid from a solid-liquid solution or liquid-liquid solution

-Fractinonal Distillation

This process can be used to separate miscible liquids with different boiling points where the liquid with the lower boiling point will vaporise first

Chromatography

Chromatography is a process used to separate the differernt components in a liquid or gaseous mixture

Using a Separating Funnel

A separating funnel can be used to separate two immiscible liquids, such as oil and water

From this topic i learnt many separation technique, this also helped me to understand some of things in my  daily life.
