→About Evaporation of Solutions
==Key Stage 4==
===Meaning===
'''Evaporation of solution''', sometimes called '''Crystallisation''' , is a technique used to [[Separating Mixtures|separate]] the [[solute]] from the [[solvent]] in a [[solution]], losing the [[solvent]].
===About Evaporation of Solutions===
'''Evaporation of solutions''' can only be used for:
*[[Separating Mixtures|Separating]] a [[solution]] to recover [[solute]]s from the [[solution]]s.
*[[Separating Mixtures|Separating]] [[insoluble]] [[solid]]s from a [[liquid]]. However, this is unnecessary as it can be done by [[filtration]].
'''Evaporation of solutions''' cannot be used for:
*Recovering the [[solvent]] from a [[solution]] - [[Distillation]]
*[[Separating Mixtures|Separating]] two [[solute]]s from each other in [[solution]] - [[Chromatography]]
*[[Separating Mixtures|Separating]] an [[insoluble]] [[solid]] from a [[soluble]] [[solid]] - [[Filtration]]
*[[Separating Mixtures|Separating]] two [[solvent]]s from each other in [[solution]] - [[Fractional Distillation]]
