explain filtration
separate an insoluble solid from a liquid by decanting or by filtration. the liquid filtrate passes through, the undissolved solid residue stays on the paper.
equipment for a filtration practical
funnel, filter paper, beaker
explain evaporation
to separate a soluble solid from a solution
equipment for an evaporation practical
evaporating basin, gauze, tripod, bunsen burner, heat mat
uses of distillation
to separate a soluble solid from a solution. if the solvent(liquid part) is required, it is obtained by fractional distillation
