Filtering is when you separate liquid from insoluble solids.

Noun: Filtration

Verb: To filter

Adjective: Filtered

Filtering cannot separate anything dissolved in a liquid.

When you filter the solid will get stuck in the filter paper and the liquid will pass through.

	You can separate mud from water in the puddle with filter paper and a funnel.


This diagram shows how the insoluble solid gets stuck in the filter paper and is called a Residue, while the liquid passes through the filter paper into the conical flask.

Only insoluble solids can be separated by filtering.

The solid trapped in the filter paper is called a residue.

The liquid that has passed through the filter paper is called filtrate.

Filtering uses a filter that has very small holes in it that allow the particles in the liquid through, but not the lumps of solid.


This diagram shows how the insoluble solid gets stuck in the filter paper while the particles in the liquid are small enough to pass through the gaps in the filter paper.

Filtration is the process of removing an insoluble solid from a mixture with a liquid.

In an experiment a mixture of insoluble solid and a liquid is filtered using filter paper. However, on an industrial scale many different types of filter can be used to separate insolubles solids from mixtures with liquids.

Filtration can only be used for:

Separating a mixture of an insoluble solid and a liquid.
Separating a mixture of a soluble solid from an insoluble solid. This is done by first adding a solvent to dissolve the soluble solid before then filtering.
