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) 1.

When you filter the mixture, sand is left as residue on the filter paper. The filtrate is a solution of sodium chloride in water since sodium chloride is soluble in water. When you evaporate the filtrate over a water bath, you are left with pure sodium chloride (or common salt) in the form of a white powder.
