Factors Affecting Solubility:
Solubility depends on....
1
Let's talk about types of solutes and solvents for Solubility...
The most common solvent is water.
Water is referred to as the universal solvent
because it can dissolve so many different substances!
The term aqueous solution means that the
solvent is WATER!

Not all solutions are liquids!

Solubility Changes with Temperature
BUT for GASES:
For most solid or liquid solutes, solubility increases as the temperature of the solvent increases.
As the temperature increases, the solubility of the gas in a liquid solvent decreases!
