Explanation:
filtration
If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble.
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered:
the sand stays behind in the filter paper (it becomes the residue)
the water passes through the filter paper (it becomes the filtrate)
The slideshow shows how filtration works:
A beaker containing a mixture of insoluble solid and liquid. There is filter paper in a filter funnel above another beaker.
