Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the water passes through the filter paper (it becomes the filtrate )
[tex]The \: techniques \: of \: dissolving, \\ filtration \: and \: evaporation \: are \: used. \\ The \: mixture \: of \: the \\ two \: solids \: is \: added \\ to \: water. \: The \: soluble \: solid \\ is \: allowed \: to \: dissolve \: and \\ the \: insoluble \: solid \: is \: filtered \\ out. \: The \: soluble \: solid \: can \\ then \: be \: obtained \: by \: evaporating \\ the \: water.[/tex]
