Answer:
1. SUMMARY. In a mixture of sand and water, the heavier sand particles settle down at the bottom and the water can be separated by decantation. Filtration can be used to separate components of a mixture of an insoluble solid and a liquid.
2. Evaporation. One way to separate a soluble solid from its solution is to make crystals. This involves evaporating the solution to a much smaller volume and then leaving it to cool. As the solution cools, crystals form, and these can be obtained by filtration.
3. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container.
4. Two immiscible liquids, oil and water, can be separated by utilizing a separating funnel. The mixtures of oil and water form two separate layers since they are totally insoluble in one another. Oil forms the upper layer while water structures lower.
