Cards

Term
colligative properties
Definition
the physical characteristics of a solution that depend on the amount of solute (i.e. concentration)
Term
van't Hoff factor (i)
Definition
the multiplicative factor that descr ibes the extent of dissociation of a solute in a solution
Term
vapor pressure lowering (Raoult's law)
Definition
the amount of vapor produced by the solvent is reduced in the presence of the solute (P = X P°)
Term
boiling point elevation
Definition
the temperature required to boil as solution is higher than that of the pure solvent (ΔTb = i m Kb)
Term
freezing point depression
Definition
the temperature required to freeze a solution is lower than that of the pure solvent (ΔTf = –i m Kf)
Term
equation for vapor pressure lowering (Raoult's law)
Definition
P = X P°
Term
equation for boiling point elevation
Definition
ΔTb = i m Kb
Term
equation for freezing point depression
Definition
ΔTf = –i m Kf
