Answer:
When you add sugar to water, the sugar crystals dissolve and the sugar goes into solution. But you can't dissolve an infinite amount of sugar into a fixed volume of water. When as much sugar has been dissolved into a solution as possible, the solution is said to be saturated.
Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.
You can see that at all temperatures, many more grams of sugar dissolve than salt. The graph also shows that the solubility of sugar increases much more than the solubility of salt as the temperature of the water increases. Alum is the least soluble until the temperature of the water increases to about 65 °C.
