By evaporating seawater
What is left behind after the evaporation of seawater?

Study Notes
- A tea strainer is used to separate insoluble tea leaves from a cup of tea.
- Melnaït o Filter paper is used to separate insoluble rice grains from a mixture of rice grains and water.
- Seawater is heated to evaporate the water, leaving behind salt. This is an example of obtaining salt through filtration.
- Water is removed by evaporation to concentrate the flavor of soup, which is also an example of filtration.
- The filtration process uses filter paper with small pores, allowing only smaller substances like water to pass through while trapping insoluble particles like rice grains or impurities in the filtrate.
- The residue, which is the solid trapped by the filter paper, can be rice grains or the impurities and dissolved solids in the case of salt production.
- Filter funnel is a tool used in the filtration process to separate the filtrate from the residue.
- Salt is obtained from seawater through the process of heating it to evaporate the water and collecting the remaining salt.
- Filter paper is used to separate dissolved solids from a liquid, leaving behind the clear filtrate.
- The pore size in the filter paper determines what particles are trapped and allowed to pass through.
- The filtration process can be used to obtain clear liquids free of impurities or particles.
