Q. What is saturated solution?
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
The amount of solute that can be dissolved in a solvent to form a saturated solution depends on a variety of factors. The most important factors are:
- Temperature: Solubility increases with temperature. For example, you can dissolve much more salt in hot water than in cold water.
- Pressure: Increasing pressure can force more solute into solution. This is commonly used to dissolve gases into liquids.
- Chemical Composition: The nature of the solute and solvent and the presence of other chemicals in a solution affects solubility. For example, you can dissolve much more sugar in water than salt in water. Ethanol and water are completely soluble in each other.
- Adding chocolate powder to milk so that it stops dissolving forms a saturated solution.
- Salt can be added to melted butter or oil to the point where the salt grains stop dissolving, forming a saturated solution.
