We obtain dissolved solid from its solution by the process of:
Filtration
Centrifugation
Melting
Evaporation
Evaporation is used to separate dissolved solid form its solution. Using this process solvent is heated to evaporate until only solid is left.
The best way to recover sugar from an aqueous sugar solution is :
(a) evaporation to dryness (b) distillation (c) filtration (d) crystallisation
