The following figure represents a solute (S, red) partially dissolved in a solvent (D, white).

 

Clicking on the following figures can be seen animations that represent four possible dynamic system processes.

After observing the animation choose one that represents a saturated solution.

	Wrong. In this animation more solute molecules are passing from the solution to the solid (crystallization)than vice versa. The solution was supersaturated.
	Wrong. In this movie there are more solute molecules passing from the solid to the solution than vice versa. The solution was not saturated.
	Right.This animation shows that during the exchange of solute molecules between the solid and the solution, the amount of solute in solution remains constant. The solution was saturated.
	Wrong. In this movie there is no exchange of solute molecules between the solid and the solution. This situation is not real.
