A solution might have properties that the original
materials did not have.
Steel is made by mixing iron and carbon. It is much stronger than the original iron.

Solids can be separated from a solution by using evaporation; the liquid part of the solution is
lost to the air.
Salt crystals left behind after the
evaporation of salt water.

Liquid water can be collected from a solution of salt water by
distillation.
