How will you separate a mixture containing sand and sugar?
✓

Answer

Sugar is soluble in water whereas sand is insoluble in water. The difference in their solubility is used to separate them. The mixture of sand and sugar is dissolved in water, then it is filtered with the help of filter paper. Sand remains as residue on the filter paper while sugar solution is obtained as filtrate. The filtrate is then evaporated to get crystals of sugar.
