what are examples of supersaturated solutions
Answers
Answer:
Supersaturated Solution
A solution is saturated when the crystallization and solvation are at equilibrium. Some solutions can be heated to create supersaturated solutions. Supersaturations are created by adding heat to a saturated solution and more solute. The solute is able to solvate with the added heat. A properly made supersaturated solution will remain solvated as the solution cools to room temperature.
Two containers, one saturated solution with extra solute. Heat is applied and cooled to give a solvated supersaturated solution.
A supersaturated solution remains solvated even with extra solid once it is cooled.

An example of a supersaturated solution is sodium acetate in water. Sodium acetate is the salt of acetic acid or vinegar. Water is a common solvent of supersaturated solutions since it can be heated safely. Supersaturated sodium acetate solution has another unique property. If the cooled solution is agitated or a seed crystal is added, the equilibrium is disrupted. The solution will rapidly crystallize. The seed crystal acts as the main point for the solution to crystallize. This reaction is exothermic and generates heat. This property has been used to create reusable heating packs. The packs when agitated solidify and generate heat. To regenerate the pack, it can be boiled to re-solvate the solution.

Example of a Supersaturated solution is sodium acetate in water.
- A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature.
- It occurs with a chemical solution when the concentration of a solute exceeds the concentration specified by the value equilibrium solubility.
- A few examples of supersaturated solutions are sodium acetate in water, thick sugar syrup, hot chocolate, etc.
