The main difference between Saturated Solution and Unsaturated Solution: A saturated solution is one in which the maximum amount of solute that can dissolve at a given temperature is dissolved. An unsaturated solution contains l
Saturated Solution vs Unsaturated Solution — Comparison Table
| Basis | Saturated Solution | Unsaturated Solution |
|---|---|---|
| Definition | Contains maximum dissolved solute at given temperature | Contains less solute than saturation point |
| Solute Addition | No more solute can dissolve; excess remains undissolved | More solute can dissolve when added |
| Equilibrium | In dynamic equilibrium with undissolved solute | Not in equilibrium with undissolved solute |
| Crystal Formation | Crystals form when cooled or evaporated | No crystal formation upon cooling |
| Concentration | Maximum concentration for given conditions | Lower concentration than saturated solution |
| Example | Water containing 36 g salt per 100 g water at 20 degrees C | Water containing 20 g salt per 100 g water at 20 degrees C |
Key Points
- Saturation depends on temperature and pressure of the system
- Increasing temperature increases saturation point for most solids
- A saturated solution appears clear but contains maximum solute
- Supersaturated solutions exist in unstable conditions
Frequently Asked Questions
What is the main difference between a saturated and an unsaturated solution?
A saturated solution holds the maximum amount of solute that can dissolve at a given temperature — no more will dissolve. An unsaturated solution holds less than that maximum, so it can still dissolve more solute.
How can you tell if a solution is saturated?
Add a little more solute and stir. If it dissolves, the solution is unsaturated; if the extra solute settles undissolved at the bottom, the solution is saturated.
Does temperature affect whether a solution is saturated?
Yes. For most solids, solubility rises with temperature, so a solution that is saturated at a low temperature can become unsaturated when heated — allowing more solute to dissolve.
