Dissolve the mixture in warm water, and filter it through filter paper. Then heat the liquid that comes through until all of it evaporates.
Work Step by Step
This question asks how we would separate a mixture of sugar and sand. To do this, we have to use the physical and chemical properties of the substances. For instance, sugar dissolves in water, while sand does not. This means that if we add water to the mixture, the sugar will be in the water, while the sand won't be. Now if we put this through filter paper, the sand will be caught in the filter, but the sugar water will pass through. Now, to turn the sugar water back into sugar, heat the sugar water. The water in it will evaporate, leaving only the sugar behind.
