The first figure shows the beginning of the interaction in which a strong solute is starting to dissolve.See the image below to visualize an unsaturated solution. Solutes in an unsaturated solution dissolve completely, leaving no remaining substrates.A solution with less solute than the solution is capable of dissolving is called an unsaturated solution.During this interaction, the outlay of crystallization is equal to the rate of disintegration (see the equal size of the red and blue arrows), resulting in a fully saturated solution.Some components of dissolvable solute are undissolved in the last container.A significant portion of strong solute (as evidenced by the blue arrows in the following measurement glass in the second figure) has broken down, but not entirely, since the crystallization process has not yet been completed.The above image shows the beginning of the immersion interaction, where the strong solute begins dissolving (as represented by the red arrows).See the image below to visualize what a saturated solution looks like. A solution is saturated when the rates of solubility and crystallization are equal and dynamic equilibrium is reached.In a saturated solution, there is so much solute present that if more were added, it would not dissolve.Solvents that can be heated safely, like water, are often used in supersaturated solutions.Sodium acetate in water, is an example of a supersaturated solution.Supersaturated solutions remain solvated even when they are cooled with additional solids.Supersaturated solutions contain more than the maximum amount of dissolved solute than the solution is able to dissolve at a given temperature. Adding just a teaspoon of chocolate syrup to a glass of milk would produce an unsaturated solution because the solute concentration is below the capacity of the solvent to dissolve.
In a saturated solution, additional solutes won't dissolve (just like the extra chocolate syrup). In this case, the syrup would be the solute, and the milk the solvent.
That’s because the milk has become a saturated solution, a solution containing the maximum concentration of one or more dissolved solutes in a solvent. Have you ever made chocolate milk with too much syrup? Some of the extra remains undissolved at the bottom of the glass.
