Final answer:

Ionic compounds in aqueous solution are best depicted as discrete ions that are individually surrounded by water molecules in a solvation process.

Step-by-step explanation:

The molecular-scale view of an ionic compound in aqueous solution is best represented by discrete ions surrounded by water molecules. In a solid state, an ionic compound forms a crystal lattice structure consisting of alternating positive and negative ions. However, when dissolved in water, the ions are separated and each becomes surrounded by water molecules in a process known as solvation. This occurs because water has a strong molecular dipole, which allows it to interact effectively with the ions. In aqueous solution, the water molecules orient themselves around the cations with their negative end and around the anions with their positive end, effectively dispersing the ions throughout the solution.
