Effect of heat would be the solvent will be dissolved fast and the temperature changes contribute to the change of the effect of the supersaturated solution.
Heat the solution
a solution which contain more solute than saturated solution
To prepare a stock solution of Leishman stain, mix the Leishman stain powder with a suitable solvent like methanol or ethanol to make a concentrated solution. Filter the solution to remove any undissolved particles. Store the solution in a dark and cool place, away from light and heat.
Under normal conditions, supersaturated solutions won't take more solute. Of course, you can heat, cool, agitate, etc., the solution to reach something called supersaturation, where solutions can be conned into taking more solute.
To prepare zinc chloride powder from an aqueous solution, you can first evaporate the water by heating the solution. This will leave behind the solid zinc chloride. Make sure to perform this step in a well-ventilated area as zinc chloride can release fumes. Collect the dried zinc chloride crystals for use as a powder.
Heat the 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.
make a fully saturated solution, then add more. after adding, greatly heat up the solution and stir it to dissolve more salt. when it cools down, you have a supersaturated solution. word of caution, if you put any kind of crystal structure in this solution, then the excess will crystalize back out.
The supersaturated solution begin to drop small crystals when the additional sodium thiosulfate was added because the supersaturated solution got reverted back to a saturated solution. Every solution has it;s own level of saturation, at a certain temperature a limit of the solute can be disolved in it, if you heat the solution the limit changes and more of the solute can be added in the solution. This is a supersaturated solution.When you drop an extra crystal into a supersaturated solution, all the extra crystals that aren't suppose to be in it crystalize out of the solution.
Yes, the compound in the packs is a supersaturated solution of sodium acetate.
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
probably a supersaturated solution if you heat it to dissolve all of the salt
Heat the solution
1. Heat the water. 2. Dissolve as much salt as possible while hot. 3. Cool the solution.
Well if you heat the saturated solution all the solids should dissolve and it should stay a colourless solution with no solids even if it does cool down to the original temperature. At this point it is supersaturated.
Put in more than it can dissolve, heat it up to force it to dissolve, then let it cool. It's now supersaturated.
Instant heat packs contain a supersaturated solution of sodium acetate that heats up when the crystallization process is started by flexing a metal disc embedded in the liquid. Since the liquid is supersaturated (concentration of a solution beyond saturation point), flexing the notched ferrous metal disc makes the solution crystallize suddenly, thereby releasing the energy of the crystal lattice.
