A saturated solution.
Saturated
Equilibrium is only found in a saturated solution, where the dissolved species and the undissolved species are in equilibrium with each other. In a dilute solution there is nothing that is undissolved, and so there is no equilibrium, and by definition a supersaturated solution is out of equilibrium and essentially has too much stuff dissolved in it (it will eventually return to equilibrium and some of the dissolved material will precipitate out).
a supersaturated solution
saturated and unsaturated solution
equilibrium ?
A saturated solution has a solute that is at its maximum concentration. At this point, no more solute can be dissolved at the current temperature. The dissolved and undissolved solutes are at equilibrium in the saturated solution.
The solution forms bigger crystals that have pointed ends.
For a short period of time they become one.
Dissolving and precipitating the solute in solvent.
When a cooled saturated potassium nitrate solution is added to water, the concentration of the potassium nitrate decreases making it less likely that he substance will precipitate out of solution.
A super saturated solution is unstable, and wants to precipitate some solute to regain a stable situation. Dissolve something in water at a high temperature in a perfectly clean glass container, until no more dissolves. Cool slowly and the solution becomes unstable because it holds more in solution than is normal at equilibrium at that lower temperature. It is super saturated. A tiny speck of dust or even agitation can provide conditions where the excess can precipitate out as a solid particles in suspension, until the equilibrium concentration of solution is reached, but with clouds of precipitate in there.
