Dissolution occurs when sugar molecules are surrounded by water molecules and the water molecules break the bonds between the sugar molecules. This causes the sugar molecules to spread out and become evenly distributed throughout the water. The resulting mixture is called a solution.
Crystallization occurs when the water molecules evaporate from a solution, leaving behind the sugar molecules. The sugar molecules then come back together and form crystals. The size and shape of the crystals depend on the rate of evaporation and the concentration of the solution.
The reversibility of sugar dissolving in water is an important concept in chemistry. It shows that some chemical reactions can be reversed, and that the products of a reaction can be converted back into the original reactants.
