Heat the solution
Heat the solution
Use really clean equipment. Heat some water in a beaker so that it will dissolve more solute. Dissolve all that it will hold, to make sure add excess. Decant the liquid into another beaker allow no crystals to be transferred to the new beaker. Allow to cool slowly. Do not agitate. The cool solution will be supersaturated.
The solubility of sodium acetate at 20 oC is 54,6 g/100 g water. If you add further solute and this is no longer dissolved the solution is supersaturated.
supersaturated solution
To make a supersaturated solution, you would first dissolve the maximum amount of solute in the solvent at an elevated temperature to increase solubility. Then, slowly cool the solution down without disturbing it to prevent the excess solute from precipitating out, creating a supersaturated solution.
No, evaporation will most likely make the solution supersaturated
The solute will eventually fall out of a supersaturated solution
The solute will eventually fall out of a supersaturated solution
To make a supersaturated solution of CdI2, you would first dissolve an excess amount of CdI2 in hot water until no more can dissolve. Then, allow the solution to cool slowly without disturbing it to prevent crystallization. Once cooled, you will have a supersaturated solution of CdI2 ready for use.
It just makes saltwater. However, you can make a supersaturated liquid by heating it, then slowly cooling it.
Supersaturated
To get a supersaturated solution you can either cool down the solution or let some of the water evaporate. To begin, make some Epsom salt crystals. These are easy to grow and you will begin to see crystals in a couple of hours. Start with one cup of warm distilled water (not boiling).
