Solubility

The amount of a compound that will dissolve in a certain amount of solvent.

Dilute Solution

A solution containing small amounts of solute in a given amount of solvent.

Concentrated Solution

A solution containing large amounts of solute in a given amount of solvent.

Molarity

A common unit of solution concentration, defined as the number of moles of solute per liter of solution.

Colligative Properties

Properties that differ based on the concentration of solute in a solvent.

Freezing Point Depression

The decrease in the freezing point of a solvent caused by the presence of a solute.

Boiling Point Elevation

The increase in the boiling point caused by the presence of a solute.

Osmosis

The flow of solvent from a lower-concentration solution through a semipermeable membrane to a higher-concentration solution.

Semipermeable Membranes

A membrane that selectively allows some substances to pass through but not others.

Osmotic Pressure

The pressure produced on the surface of a semipermeable membrane by osmosis.
