Filtration. This technique is used to separate an undissolved solid from a mixture of the solid and a liquid / solution ( e.g. sand from a mixture of sand and water) . Centrifugation can also be used for this mixture; A filter paper is placed in a filter funnel above another beaker; The mixture of insoluble solid and liquid is poured into the filter funnel
