How can evaporation be used to separate substances mixed in solution?

Large pieces of insoluble substances will often settle out of a mixture of a solid and a liquid. To separate a solid solute from a solvent (like salt from water), you used evaporation. At room temperature, water evaporates from a solution very slowly.

How do you separate a mixture?

SEPARATING MIXTURES. The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances. Tea leaves do not dissolve in water, so you can use a strainer to FILTER them.

How do you separate the substances in a mixture?

Distillation uses boiling to separate mixtures of liquid solutions. It takes into account that different substances in the mixture will have different boiling points. For example, if you heat salt water the water in the solution will boil before the salt. The water will then evaporate leaving the salt behind.
