Supersaturation

is important for crystallisation.

Crystallisation

is the process where a substance previously in solution comes out of the solution.

solubility of other reactants

The is less affected by temperature and all remain soluble in cold water.

Hot air

is pumped in the same direction.

calcium chloride

The is hygroscopic which means it attracts water and holds it removing it from the mixture.the remaining liquid can be separated by filtration.

maximum amount of solute

Saturated solution: a solution that contains the possible.

mixture of liquids

Water can be removed from a(n) by adding solid anhydrous calcium chloride.

freeze dryer

Freezing in a(n) to a temperature lower than either product or waters freezing point.

saturated solution

a solution that contains the maximum amount of solute possible
