What is Solubility and Saturated Solutions?
Within Chemistry, which covers atoms, bonding, reactions, the periodic table, organic chemistry and the chemistry of everyday life, this topic explains Solubility and Saturated Solutions. Chemistry links what you can see in the lab to the particles and bonds behind it, so each topic here shows that link in a model.
Check that you can explain Solubility and Saturated Solutions in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Solubility and Saturated Solutions helps you explain why substances behave as they do, from cleaning products and food to medicines.
Solubility and Saturated Solutions in detail
Solubility is the maximum mass of a solute that dissolves in 100 g of solvent at a given temperature. A solution is saturated when no more solute will dissolve. For most solids, solubility increases with temperature, while for gases it decreases, so warm water holds less oxygen.
Solubility curves plot solubility against temperature and let you predict how much crystallises when a hot saturated solution cools. Like dissolves like: ionic and polar substances dissolve in water, but non-polar substances such as oil do not and dissolve in organic solvents. Solubility affects drug delivery and cleaning.
