A supersaturated solution will not accept any more solid solute molecules into the dissolved state for the exact same reason that a saturated solution cannot; it is saturated like a sponge that cannot absorb and contain any more water.
The explanation directly involves the concept called equilibrium. Place a handful of sugar in two cups of water and the size of the pile of sugar will diminish only up to a point. The reason this point is called equilibrium is to reflect the facts that the rate of solute atoms leaving (exiting) the pile - dissolving - is equal to the rate of solute atoms rejoining (entering) the pile - crystallizing.
Raising temperature will increase the level of solute concentration needed to create a saturated solution. Decreasing this temperature, without removing solute from the cooled solution, gives a supersaturated solution.

What are the types of solutions according to solubility?
The types of solutions based on solubility are saturated, unsaturated, and supersaturated. A saturated solution contains the maximum amount of solute that can dissolve in a solvent at a given temperature. An unsaturated solution can dissolve more solute, and a supersaturated solution contains more solute than it normally would at a particular temperature.
Supersaturated means that a solvent can dissolve solute than at a lower temperature?

What is the meaning of the terms saturated unsaterated and supersaturated?
Saturated, unsaturated, and supersaturated refer to the concentration of solute in a solution. A saturated solution contains the maximum amount of solute that can dissolve in a solvent at a given temperature, leading to equilibrium between dissolved and undissolved solute. An unsaturated solution has less solute than this maximum, allowing more solute to dissolve. A supersaturated solution contains more solute than can typically dissolve at that temperature, achieved by altering conditions such as temperature, and is often unstable.
When reading a solubility curve the area above the line or curve represent?
The area above a solubility curve represents supersaturated solutions, where the concentration of solute exceeds the maximum amount that can dissolve at a given temperature. In this region, excess solute may precipitate out of solution if disturbed. Conversely, the area below the curve indicates unsaturated solutions, where more solute can still dissolve.
A solution having a high amount of the solute?
A solution with a high amount of solute is considered concentrated. This means there is a large quantity of the solute dissolved in the solvent. Concentrated solutions usually have a higher concentration than diluted solutions.
What are the three kinds of solution?
The three types of solutions are: saturated (contains the maximum amount of solute that can dissolve at a specific temperature), unsaturated (contains less solute than the maximum amount that can dissolve), and supersaturated (holds more solute than it should at that temperature, often created by cooling a saturated solution).
What kind of solution is an unstable system?
Supersaturated solutions tend to be unstable. This is largely due to the fact that one is putting more solute than would normally dissolve at that temperature.
What is supersaturated solution what is done to make a solution supersaturated?
A supersaturated solution is a solution that contains more solute than it can normally dissolve at a given temperature and pressure. To create a supersaturated solution, a solvent is heated to dissolve a greater amount of solute than possible at cooler temperatures, and then the solution is carefully cooled. As the temperature decreases, the solute remains dissolved beyond its normal saturation point until disturbed, after which it may crystallize out.
What is the best way to make a supersaturated solution?
Heat the solution
Explain what is incorrect with a students thinking if he or she believes that stirring alone will allow more solute to dissolve in a saturated solution?
Stirring does not increase the solubility of a solute in a saturated solution. In a saturated solution, the maximum amount of solute that can dissolve has already been reached. Stirring only helps in evenly dispersing the solute particles within the solution, but it does not increase the amount of solute that can dissolve.
Why you need to heat the solution in order to prepare supersaturated solution?
Heating the solution increases the solubility of the solute, allowing more of it to dissolve. This creates a supersaturated solution, where the solution is holding more solute than it normally can at that temperature. Upon cooling, the excess solute remains in solution, resulting in a supersaturated solution.
What happens when you add solute to supersaturated solution?
The solute can re-form as a solid.
