=> separation of insoluble solids and liquids *soluble means can be dissolved in water
HEATING TO DRYNESS/ EVAPORATION:
eg. salt water => heated to dryness => salt
However, some compounds decompose when heated to dryness!
eg. sugar=>carbon
CRYSTALLISATION:
=> Collect pure solid(soluble) * if solid is thermally unstable, it must be heated indirectly
Saturation
-->When no more sugar can be dissolved
--> changes as temperature changes
*Table Salt CANNOT be crystallised*
