Interpretation: The reason is to be explained whether a solution with undissolved solute can be supersaturated or not.
Concept Introduction:
For understanding supersaturated solutions, one should need first understand the different types of solutions:
A solution that can dissolve more solute is said to be unsaturated. There are no visible lumps of undissolved solute in such a solution since all of the solutes are completely dissolved.
Any more solute will now be visible in the solvent as chunks of undissolved particles because a saturated solution is no longer capable of dissolving it. Similar to an unsaturated solution, a saturated one has no undissolved particles; but, at this stage, no additional solute can be dissolved. Between the solute's dissolution and its re-crystallization, there occurs a dynamic equilibrium.
A saturated solution can be made supersaturated by adding additional solute. Undissolved solute particles will now be apparent in the solution. When a solution contains more solute than it is capable of dissolving at a specific temperature and volume, the solution is said to be supersaturated.
Answer to Problem 52A
Supersaturated solutions are any liquids that contain more solute than is necessary to generate a saturated solution at any given constant temperature.
The undissolved solute cannot be present in a supersaturated solution since doing so would reveal that it is a saturated solution.
Explanation of Solution
A supersaturated solution is in a meta-stable state, meaning that as long as it is not disturbed, it will stay that way. It will become a saturated solution in the presence of a small perturbation (such as a slight temperature rise or fall).
For example:
Assume the substance,
The solute will all dissolve if the solution is heated to a high enough temperature, but the solution will still be saturated or unsaturated. When all
As a result, a supersaturated solution is unstable, and even a small physical disturbance might result in the crystallization of the extra dissolved solute
A supersaturated solution cannot contain undissolved solids in it. For making a supersaturated solution, the solute should be dissolved at a particular undisturbed state.
