Describe three ways mixtures can be separated. Give an example for each method.
- Filtration: This method separates an insoluble solid from a liquid using a filter medium that allows the liquid to pass through but retains the solid.
  - Example: Separating sand from water.
- Evaporation: This method separates a soluble solid from a liquid by heating the mixture, causing the liquid to turn into vapor and leave the solid behind.
  - Example: Separating salt from water.
- Decantation: This method separates an insoluble solid from a liquid, or two immiscible liquids, by carefully pouring off the top layer after the components have settled.
  - Example: Separating oil from water or sand from water (after sand has settled).
A cup contains sand, salt, and water. Explain step by step how you would separate all the components.

Dissolving and Decantation/Filtration (to remove sand)

*   Add more water to the mixture in the cup and stir well. The salt will dissolve in the water, forming a salt solution, while the sand, being insoluble, will settle at the bottom.
*   Carefully decant (pour off) the salt solution into another container, leaving the wet sand behind. Alternatively, pour the mixture through a filter paper in a funnel. The sand will be trapped on the filter paper, and the salt solution will pass through as the filtrate.

Evaporation (to separate salt from water)

*   Heat the salt solution (the filtrate from Step 1) in an evaporating dish. The water will evaporate, turning into steam and leaving the solid salt crystals behind in the dish.
*   Collect the steam by condensation if pure water is also desired (distillation), otherwise, the water is lost to the atmosphere.
*   The separated components will be **sand**, **salt**, and **water** (if condensed).
