Question

Why cannot we separate salt solution by filtration?

Answer 1

HEYA!!
-----------

➡We cannot separate salt and water solution by filtration ✔. This is because slat is completely soluble in water . They form a homogeneous mixture.

➡Filteration on the other hand can be used to separate only mixtures that are not soluble in each other . for example, it can be used to separate Sand and water .


➡Salt can be separated from water by Evaporation.

Answer 2

The salt solution can pass through the small holes in the filter paper because all the particles are tiny. ... The Solution is heated so that the water evaporates, leaving the salt behind.Filtration is often used to separate the solid and liquid parts of a suspension. The liquid part is called the filtrate.
