describe the chemical or physical separation methods

Three methods used to separate salt and sand are physical separation picking out pieces or using density to shake sand to the top, dissolving the salt in water, or melting the salt. Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to ...
