01
Measure approximately 20g of ammonium chloride and 50cm^3 of distilled water.
On an electric weighter measure 20g of ammonium chloride. It does not have to be exactly 20g and 50cm^3.
02
Mix ammonium chloride and distilled water.
Ammonium chloride won't get melted easily. So we used a magnetic stirrer.
03
Move the ammonium chloride solution into a beaker and deep it into ice water
Now observe!
How and Why did this happen?
The amount of ammonium chloride that can be dissolved in water increases as the temperature increases. The state in which ammonium chloride, that is, the solute, is dissolved as much as possible in water, that is, the solvent, is called saturation. As the temperature of the solution decreases, the solubility decreases, so the solute is crystalized equal to the difference in solubility.
Crystalisation refers to the creation of a solid phase in a liquid or solid phase and separation from the original phase. Crystalisation occurs when a pure liquid is cooled below its freezing point or when a third component is dissolved when the solution is cooled.
