A supersaturated solution has a concentration of solute greater than the solubility at a specific temperature.
A supersaturated solution is obtained.
A supersaturated solution is one that contains more solute than can typically dissolve at a given temperature and pressure. In this case, the flask that contained a supersaturated solution before the addition of NaCl would be the one where the solute was present in excess, beyond its normal solubility limit. The addition of NaCl would likely cause the excess solute to precipitate out, indicating the solution was indeed supersaturated.
A supersaturated solution of sodium chloride in water at 20 oC appear after a concentration of 360 g NaCl/L water.
The solubility of sodium chloride is 360,9 g/L at 20 0C; after this concentration the solution is supersaturated.
The solute will eventually fall out of a supersaturated solution
The solute will eventually fall out of a supersaturated solution
Adding more solute the solution become supersaturated.
Supersaturated
A solution become supersaturated when the limitt of solute solubility at a given temperature is exceeded.
When you raise the temperature of a saturated solution; you can add more solute and make it a super saturated solution because the molecules of the solvent will be able to attract more molecules of solute.
NO it is not
Probably with enough heat. Solutions can become supersaturated. "Supersaturated solutions are prepared or result when some condition of a saturated solution is changed, for example temperature, volume (as by evaporation), or pressure." -Wikipedia as a source
