A supersaturated solution is when there is more solute present in the solution than can be absorbed by the solvent. When it is disturbed, all of the solute that is not in solution falls out, sometimes forming crystals.
A precipitate forms because the solvent has dissolved the maximum amount of solute and can no longer dissolve the excess. The excess therefore forms a precipitate. You can think of it this way. Imagine you are cleaning up juice that you spillt with a sponge. After a while the sponge becomes so filled with juice that it cannot soak up any more, or in other words the sponge becomes saturated with juice. In a similar way, after a while a solvent will no longer be able to "soak up" any more solute and the solute will remain as a precipitate.
it can become supersaturated by raising the temperature
i hope that helped. :) (Y) peace (Y) (:
No
For example by the reaction of an acid with a metal, the reaction of two salts, etc.
The evidence that elements can combine to form new compounds is seen in combining two liquids to form a solid. This will form an insoluble compound from a soluble aqueous solution.
The saturated solution of sodium chloride is 379,3 g for 1 kg solution at 8o oC.
Precipitates form whenever two insoluble ions are in solution, thereby leaving solution. They can form either gases or solids (usually solids).
creation of solid in a solution
If you think to a precipiate this is possible when the compound is insoluble in the solvent.
By precipitation out of a saturated solution or by evaporation from a saturated solution.

This is an insoluble or covalent compound.
Precipitates form quickly because when an insoluble substance is introduced into a solution, the insoluble soulution's density is to be greater.

Add something that magnesium will form an insoluble compound with. Sodium sulfate or potassium carbonate, maybe.
Iron, in solution, can form chelates; the insoluble oxides not.
In a solution, lead (II) acetate (Pb(II)Ac2) and sodium carbonate (Na2CO3) will react to form Pb(II)CO3, an insoluble compound that will form a precipitate. The Na+and Ac- will remain in solution.
