if 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.
