What happens to a solution when it is supersaturated?

Answer 1

A saturated solution can dissolve more when you increase its temperature and less when you decrease. When hot saturated solution is cooled to zero degrees Celsius, or beyond it the solubility of the solvent will decrease and precipitate until it forms a solid.

A saturated solution is one that has reached its saturation level for a specific solute (what is dissolved in it). The saturation level depends on the temperature and different solutes have different saturation levels at different temperatures.

When a saturated solution is cooled, one of two things can happen.

• If the temperature drop reduces the saturation level, the liquid will be supersaturated and some of the dissolved substance will precipitate out of the solution and you will eventually see particles or crystals floating on top or settling on bottom of the liquid.
• If the temperature drop is slow enough and the liquid is not disturbed, it may become supersaturated but retain the solute. The amount of solute will exceed the saturation level. Any disturbance can start the precipitation such as shaking or dropping something into the solution.

Answer 2

It depends on how the solution is hot and how far it is cooled. A liquid's saturation point is defined by the capability of dissolving particular solute at standard temperature and pressure (STP). It can dissolve more when you increase temperature and less when you decrease. Thus, when a hot saturated solution is cooled down to STP and beyond it the solubility of the solvent will decrease and excess solute amount will precipitate and form a solid.

Answer 3

When a solution is supersaturated, it contains more solute than it can normally dissolve at that temperature. This causes the solute to precipitate out of the solution and form solid crystals. Factors such as temperature changes or the introduction of a seed crystal can trigger this precipitation process.

Answer 4

In Chemistry when a supersaturated solution begins to cool down the supersaturated solution begins to crystallization occurs in the solution.

Answer 5

Solubility decreases and a precipitate forms

Answer 6

It has more dissovled solution than water

Answer 7

the solid reacts with the liquid
