What is a saturated solution?
The prefix "Super-" means overcoming while the date of saturation means inserting as much of something as it is usually possible to hold something else. SuperSaty solution is produced when the substance - dissolved substance - dissolves in water or another solvent to the extent that it is usually not possible. Most substances form a saturated solution with difficulty. The moved solution is generally achieved by changing the conditions of saturated solution. The evaporation of some solvents in a very clean environment can achieve the purpose as a suitable change in the solution may be appropriate.
As part of the solvent evaporates from the solution, this solution develops an increased ratio of solut to the solvent. If the initial solution was previously saturated, it becomes exaggerated. Most substances increase solubility with temperature rise and solubility decrease when the temperature is lowered. For these substances saturated soluble when the temperature is lowered, saturated. The opposite applies to substances that reduce solubility with increasing temperature and increase of spancore with temperature decreased; If one of them was in a saturated state, it will no longer be at a lower temperature.
Superycencyd solutions are inherently unstable and respond in a way as with super chilled liquids; Many people have experienced a phenomenon of super -cooled water. If clean water is sufficiently cooled and the container is kept at rest and is clean and without scratching, the temperature may be below the freezing point without the formation of the ice- Place the scratched or dirty object in the water and can solidify in just moments. This is because scratches and particles provide interfaces of point and lines where crystals can nucleate and grow. Similarly, intronamine several dust particles or small crystals into a saturated solution and at mere moments of a solid mold at the bottom of the container and leaving an ordinary saturated solution.
One commercial product for outdoor use uses a traineeT SuperSaturation. It is a chemical heating pad or hand alcohol that uses simple sodium acetate. This chemical salt easily forms a saturated solution when maintained without dust and crystals. If the housing contains this solution, it dropped several small acetate crystals into it, the moved solution quickly returns to saturated by throwing an excess melted substance. Because the reaction is exothermic - heat production - the solution warms the hands or pockets of the person who holds the housing.
