Evaporation
Evaporation is the process in which the solvent of a solution is converted into
a vapour to leave a solid or liquid solute. There are many applications of
evaporation, ranging from the slow evaporation of water from a solution of
an ionic compound to leave hydrated crystals, e.g. crystallization of
CuS04.5H20, to the evaporation of large volumes of low-boiling-point
solvent under reduced pressure in the extraction of an organic compound.
Since crystallization by evaporation is a specific technique for a relatively
small range of compounds, the term evaporation is generally interpreted as
the removal of the solvent from a solution.
