Solubility Flashcards
What is solubility?
The amount of solute that can dissolve in a solvent at a certain volume and temperature
By definition, it is the maximum mass (g) that can dissolve in 100g of solvent.
How does temperature affect solubility?
Solubility increases with temperature
As temperature increases, there are wider intermolecular spaces, allowing more solid to dissolve.
How does pressure affect the solubility of gases?
Solubility of gases increases with pressure
As pressure increases, gases become more soluble.
Define solute.
A substance that dissolves in a solvent.
Define solvent.
What the solute dissolves in.
What is a solution?
A mixture of the solute dissolved in solvent.
What is a saturated solution?
When the maximum amount of solute has been dissolved in a solvent at a certain volume and temperature.
What does a solubility curve show?
Solubility in g of solute/100g of water over temperature.
