Saturated Solution vs. Unsaturated Solution — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 26, 2023
Saturated Solution contains the maximum amount of solute that can dissolve at a given temperature. Unsaturated Solution can dissolve more solute at the same temperature.

Key Differences
In a Saturated Solution, the solvent has absorbed the maximum amount of solute it can at a particular temperature. This means no more solute can be dissolved unless the temperature changes. On the other hand, an Unsaturated Solution is one where there's still room for more solute to be dissolved at the given temperature. It hasn’t reached its limit.
In the context of chemistry, a Saturated Solution represents equilibrium between dissolved and undissolved solute. Conversely, an Unsaturated Solution indicates the absence of such equilibrium, suggesting that solute can still be added and dissolved successfully.
To visualize, imagine a glass of water with salt. If you keep adding salt and it all dissolves, you have an Unsaturated Solution. But once you add so much salt that no more will dissolve, you have a Saturated Solution. In both scenarios, it's crucial to understand that temperature plays a vital role; as temperature increases, most solvents can dissolve more solute.
Another significant distinction lies in their applications. While Saturated Solutions are often used as references in laboratories because of their consistency, Unsaturated Solutions are typically used when there's a need to dissolve more solute, as they haven’t reached their solubility limit.
To further simplify, if a Saturated Solution is like a fully packed elevator, an Unsaturated Solution is like an elevator with space for more passengers. Both are integral in various scientific and industrial processes, each offering its unique set of characteristics.

Comparison Chart
Solubility Status
Has reached its solubility limit at a given temperature.
Has not reached its solubility limit at that temperature.
Equilibrium
Exists between dissolved and undissolved solute.
No such equilibrium; more solute can be dissolved.
Appearance
May have undissolved solute at the bottom if excess is added.
Lacks undissolved solute as more can be dissolved.
Application
Often used as reference in labs due to consistency.
Used when more solute needs to be dissolved.
Response to More Solute
No more solute will dissolve unless conditions change.
More solute can be dissolved until it becomes saturated.
Compare with Definitions
Saturated Solution
A solution with maximum dissolved solute for a given temperature.
Sea water is often a Saturated Solution of salt.
Unsaturated Solution
A solution that can dissolve more solute at a particular temperature.
Tap water is an Unsaturated Solution as it can dissolve more sugar.
Saturated Solution
Represents equilibrium between dissolved and undissolved substances.
A Saturated Solution of calcium carbonate will have some settled at the bottom.
Unsaturated Solution
Lacks equilibrium between dissolved and undissolved substances.
An Unsaturated Solution of salt will readily dissolve more salt crystals added to it.
Saturated Solution
A state where solvent's dissolving capacity is reached.
A Saturated Solution of salt means water can't dissolve more salt at that temperature.
Unsaturated Solution
A state where the solvent has more capacity to dissolve solute.
An Unsaturated Solution of sugar means you can add and dissolve more sugar.
Saturated Solution
A solution where added solute no longer dissolves.
If you keep adding sugar to iced tea and it stops dissolving, you have a Saturated Solution.
Unsaturated Solution
A solution capable of dissolving additional solute under specific conditions.
If you add sugar to water and it dissolves completely, it remains an Unsaturated Solution.
Saturated Solution
A solution not capable of dissolving additional solute under specific conditions.
At room temperature, if sugar remains undissolved in a solution, it’s a Saturated Solution.
Unsaturated Solution
A solution that hasn't reached its solubility limit.
Freshwater is typically an Unsaturated Solution for most salts.
Common Curiosities
Do Saturated Solutions always have undissolved solute?
No, but if excess solute is added beyond its saturation point, it won’t dissolve.
What is an Unsaturated Solution?
An Unsaturated Solution can dissolve more solute at the same temperature.
Can more solute be added to a Saturated Solution?
No, not unless conditions, like temperature, change.
What is a Saturated Solution?
A Saturated Solution contains the maximum amount of solute that can dissolve at a specific temperature.
Can an Unsaturated Solution become saturated by reducing temperature?
Yes, decreasing temperature can reduce solubility, making the solution saturated.
Is the equilibrium constant for a Saturated Solution always the same?
It can vary based on conditions like temperature and pressure.
Does stirring affect the state of an Unsaturated Solution?
Stirring can speed up dissolving, but it won’t change its unsaturated nature until solubility limits are reached.
Are all solutions either Saturated or Unsaturated?
Solutions can also be supersaturated, where solute concentration is beyond the saturation point due to specific conditions.
How can you change an Unsaturated Solution to a Saturated Solution?
By adding more solute until no more dissolves.
Are Saturated Solutions commonly found in nature?
Yes, examples include sea water being a Saturated Solution of salt.
Can you easily convert a Saturated Solution to an Unsaturated Solution?
Yes, by diluting it with more solvent or increasing the temperature.
How does temperature impact an Unsaturated Solution?
As temperature increases, most Unsaturated Solutions can dissolve more solute.
Why does solubility limit exist in a Saturated Solution?
It's a balance between the rate of dissolution and the rate of crystallization.
How is concentration related to an Unsaturated Solution?
An Unsaturated Solution has a concentration below its maximum solubility at that temperature.
Can pressure affect the state of a Saturated Solution?
Yes, especially for gases. Increasing pressure often increases solubility.
