how mixtures can be separated by crystallisation
Answers
Answer:
When a product is made as a solution, one way to separate it from the solvent is to make crystals. This involves evaporating the solution to a much smaller volume and then leaving it to cool. As the solution cools, crystals form, and these can be obtained by filtration.

Answer:
Crystallisation
Crystallisation is used to produce solid crystals from a solution. When the solution is warmed, some of solvent evaporates leaving behind a more concentrated solution
Explanation:
To obtain large, regularly shaped crystals from crystallisation, also:
put the solution in an evaporating basin
warm the solution by placing the evaporating basin over a boiling water bath
stop heating when crystals begin to form around the edge of the basin
After the remaining solution has cooled down, pour the excess liquid away (or filter it). Dry the crystals using a warm oven or by patting them with filter paper.
