The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.
Everyday Examples of Saturated Solutions
- Carbonated water is saturated with carbon, hence it gives off carbon through bubbles.
- Adding sugar to water until it no longer dissolves creates a saturated solution.
- Continuing to dissolve salt in water until it will no longer dissolve creates a saturated solution.
- The Earth's soil is saturated with nitrogen.
- Mixing powdered soap into water until it will not dissolve creates a saturated solution.
