Dilute, saturated, and super-saturated.


With nothing in a solvent, it is simply a liquid. Adding a solute creates a "solution". When the liquid has the capacity to dissolve more of the solute, it is a dilute, or unsaturated solution.

When the liquid contains as much of a solute as it can be the solute would precipitate out as a solid, it is saturated.

In some conditions of preparation solutions can be made that contain MORE solute than would normally be expected before precipitation. These are super-saturated solutions.

Usually, the addition of a nucleation point by addition of a crystal, or even a shock wave, will induce a rapid automatic precipitation of the excess solute.
