So this is an example of an ideal dilute solution. In this example, the sodium and a chloride are separated by water molecules so they can't interact. This is an example of a nonideal dilute solution. In this example, the sodium and the chloride are able to interact with each other, so therefore, it's non. Ideal dissolving is a process by which solvent molecules break apart solvent molecules from one another. Now, in the solvent, there's water.
