This is a fun question. Combining water (as a solvent) and salt or sugar (as solutes) is a study in molecular saturation and dilution. There are a number of simple and real life chemistry experiments you can conduct right in your own kitchen to study the properties of solids and liquids under certain conditions. Kids and adults alike can learn much about science from a few minutes of mixing and observing sugar and water.

Molecules form three dimensional shapes and have certain attractions (or repulsions) from different molecules when combined. This explains why laundry detergents can clean food and grass stains. One water molecule is made up of hydrogen, and oxygen, with a chemical formula of H2O. A molecule of salt contains chlorine and sodium. The chemical formula for this salt is NaCl. One molecule of sugar contains carbon, hydrogen, and oxygen. The chemical formula for sugar is C12H22O11.

Salt is called an Ionic Solid. It is made up of molecules that have a strong opposite attraction to one another. When a mixture of salt and water is saturated, this means that the water can no longer dissolve any more of the salt molecules. Or, more specifically, the water molecules can no longer surround and pull apart (via polarity) or disperse the individual salt molecules. Importantly, if the water then is taken away from the salt mixture - evaporated at the same temperature, for example - the salt's sodium and chloride bonds reform and it remains as a solid substance.

Can we dissolve sugar in this saturated mixture of salt and water? Sugar molecules have different shapes and properties than salt molecules. Sugar is called a Molecular Solid, referring to its weaker intermolecular bonds. Sugar dissolves in water differently than salt and therefore it will be able to dissolve in a saturated salt solution.

I think it's possible. From what I remember, because the saturated solution from dissolving the salt is an ionic disassociation and not molecular, there are still resources for the molecular disassociation of the sugar molecules. The solubility of the sugar may not be as high, since the solution is no longer regular water.

You could also dissolve the sugar using with a "supersaturated solution" by heating the liquid first.
