How would the molecular (microscopic) level of salt and sugar look when dissolved in water?

Answer:

Well, #NaCl(aq)# involves bond breaking, and #C_6H_12O_6(aq)# involves solvation.......

Explanation:

When an ionic salt dissolves in water (or some other polar solvent), bond breaking is conceived to occur. For salt, in water, the strong electrostatic bond between #Na^+# and #Cl^-# ions are broken, and ion-dipole complexes with the water molecules result. As far as anyone knows, we could represent these as #[Na(OH_2)_6]^+# and #[Cl(H_2O)_(4-6)]^-#.

On the other hand, when sugar dissolves in water, NO chemical bonds are broken, and the polar hydroxyl groups of the sugar molecule are solvated by water molecules.
