A saturated solution.
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).
D. A saturated solution. In a saturated solution, the rate of dissolution of solute is equal to the rate of precipitation of solute, leading to a state of dynamic equilibrium between the dissolved and undissolved solute.
That is called a saturated solution, where no more solute can dissolve into the solvent at that temperature.
A saturated solution is considered a type of solution. It occurs when the maximum amount of solute has dissolved in a solvent, resulting in a dynamic equilibrium where solute particles continue to dissolve and precipitate at equal rates.
For a short period of time they become one.
A saturated solution
The evidence that the equilibrium shifted when a saturated potassium nitrate solution was cooled is the precipitation of potassium nitrate crystals. Cooling the solution causes a decrease in solubility, leading to excess solute (potassium nitrate) to precipitate out of the solution. This indicates that the equilibrium has shifted towards the solid phase as a result of the change in temperature.
A solution with a concentration above the equilibrium solubility is called supersaturated. This means that the solution contains more solute than it should be able to hold at that given temperature.
A saturated solution
A saturated solution is at equilibrium, meaning the rate of dissolving solute is equal to the rate of precipitating solute. As a result, no more solute can dissolve in the solution at that specific temperature and pressure. This makes the concentration of the solute in the saturated solution constant.
A saturated solution has achieved equilibrium between solute and solvent when the solute is still visible after mixing. This means that the solvent has dissolved as much solute as it can at that particular temperature and pressure, resulting in a saturated solution.
