No. A saturated solution is still in equilibrium. If you bring it into contact with more of the solute, the concentration will remain the same. Solute will precipitate out at the same rate that more solute dissolves into the solution.
An unstable equilibrium would be a supersaturated solution. In a supersaturated solution, more of the solute is in solution that would be equilibrium with the solid solute (or gas if you are dissolving gas for example). An example that many people are familiar with is dissolving a lot of sugar into hot water. As it cools down, the solution becomes supersaturated. As long as there is nothing for the sugar to nucleate on , the sugar can remain in solution indefinitely. If you hang a string in the solution, the sugar will start crystalizing on the string, forming "rock candy."

For a short period of time they become one.
equilibrium is reaching that state of equal concentration. isotonic is how you describe the cell that has equal concentration.
This solution is called a saturated solution, when the solution will dissolve no more of a solute.
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.
The easiest way to determine if the solution is saturated or not is not really very 'scientific.' Remove a sample and, drop a bit of the solute into it. If the additional solute dissolves, the solution is not saturated. If it does not, the solution is saturated.
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.
