Filtration and Evaporation

The video tutorial demonstrates how to separate a mixture of salt and sand using filtration and evaporation. It explains the process of dissolving salt in water, filtering out sand, and then evaporating the water to retrieve the salt. The tutorial highlights the scientific principles of solubility and filtration, and provides real-world examples of salt extraction through evaporation in salt flats.
