Example 1

easy
List four common methods for separating mixtures and give an example of when each would be used.

Solution

  1. 1
    Filtration: separates an insoluble solid from a liquid (e.g., sand from water using filter paper).
  2. 2
    Evaporation: recovers a dissolved solid by boiling off the solvent (e.g., obtaining salt from salt water).
  3. 3
    Distillation: separates liquids with different boiling points (e.g., separating ethanol from water).
  4. 4
    Magnetism: separates magnetic materials from non-magnetic ones (e.g., iron filings from sand).

Answer

Filtration, evaporation, distillation, magnetism\text{Filtration, evaporation, distillation, magnetism}
All mixture separation techniques exploit differences in physical properties between the components. No chemical changes are involved — the original substances are recovered unchanged.

About Mixture Separation

Physical methods used to isolate the individual components of a mixture by exploiting differences in their physical properties such as particle size, boiling point, density.
