Molality

Freezing Point Depression

the phenomenon that occurs when the freezing point of a liquid (a solvent) is lowered by adding another compound to it, such that the solution has a lower freezing point than the pure solvent

Colligative Properties

properties of solutions that depend on the number of particles in a volume of solvent and not on the mass of the particles

Boiling Point Elevation

The phenomenon that occurs when the boiling point of a liquid (a solvent) is increased when another compound is added, such that the solution has a higher boiling point than the pure solvent. it occurs whenever a non-volatile solute is added to a pure solvent

Van't Hoff Factor

a factor 'i' to express the extent of association or dissociation of solutes in solution

Molality

a unit of concentration, defined to be equal to the number of moles of solute divided by the number of kilograms of solvent
