उत्तर

We will use filtration to separate a mixture of sand and sugar. Sugar dissolves in water but sand does not. These properties of sugar and sand allow them get separated by filtration.

In filtration, suspension can be filtered using a filter paper leaving sand as residue on the filter paper. Now, the filtrate contains sugar only.  Sugar can further be recovered from the filtrate.
