Video Transcriptif we have a supersaturated solution of a particular salt or of any compound that could even be a molecule such as sugar, then we have more of the solute dissolved in the solution, then is thermo dynamically stable? So it wants to come out of solution just like a ball wants to roll down the hill. However, sometimes we need to initiate it to initiate the precipitation of a salute in a supersaturated solution. one way is to add some salute and if you've seen the demonstration of supersaturated sodium acetate, the way it is initiated is by adding some salute. Another way is to agitate the solution. We can agitate the solution by shaking it. We can agitate it by taking a stirring rod, sticking it in and stirring it or scratching the site of the glass to form a new creation site where precipitation can occur. So the answer to this question then ends up being the two answers, adding more solute or agitating the solution. The answer is C. Which is both A and B.

Bullard Publisher:WILEY How can a supersaturated solution be made?An aqueous solution can be rendered supersaturated by first dissolving the solute in water at an elevated temperature using enough to give a concentration just under its solubility at that temperature. After the last of the solute crystals have dissolved the solution is cooled.
How does a supersaturated solution dissolve?A solution of a chemical compound in a liquid will become supersaturated when the temperature of the saturated solution is changed. In most cases solubility decreases with decreasing temperature; in such cases the excess of solute will rapidly separate from the solution as crystals or an amorphous powder.
How crystallization occurs in a supersaturated solution?When a solution that has had more solute dissolved at a higher temperature is now cooled, it becomes supersaturated at the lower temperature. Because that supersaturated solution holds more solute than is stable at the lower temperature, crystals start to form.
How can you make a saturated solution from a supersaturated solution?You can evaporate the solvent by permitting air circulation or by heating the solvent. Add a seed crystal to a supersaturated solution. The seed crystal will cause the solute to precipitate, leaving a saturated solution.
