COLLIGATIVE PROPERTIES Flashcards
(29 cards)
are properties that depend only on the number of solute particles in solution and not on the nature of the solute particles
Colligative Properties
is the pressure exerted by a vapor in equilibrium with its condensed phase, either
liquid or solid, at a particular temperature
Vapor Pressure

Solutions conduct electricity because of the free flow of electrons in their structure
Electrolyte Solution
In an electrolyte solution, the number of dissolved particles is larger because the
solute breaks apart into ions
The greater the number of ions, the
larger the impact on colligative properties will be
are those in which the solute does not dissociate into ions when dissolved
Nonelectrolyte solutions
are those in which the solute does not dissociate into
ions when dissolved
Nonelectrolyte solutions
the movement of a solvent through a semipermeable membrane from low
solute concentration to high solute concentration
Osmosis
The excess hydrostatic pressure is called
osmotic pressure
equation for osmotic pressure
Van’t Hoff Equation
Two solutions having same osmotic pressure are said to be
Isotonic
Two solutions having different osmotic pressure, the solution with lower osmotic pressure is said to be
Hypotonic
while the one with larger osmotic pressure is said to be
hypertonic
dissociate into ions in solution
electrolytes
is made up of one or more cations and one or more anions held together by electrostatic forces
Ion Pair
are characteristic properties that depend on the identity of the solvent
cryoscopic constant (kf) and ebullioscopic
A property that depends only upon the number of solute particles (concentration), and NOT upon their identity
Colligative Property
The difference in temperature between the freezing point of a solution and the freezing point of the pure solvent (water)
Freezing-Point Depression
The temperature at which the vapor pressure of the liquid phase equals atmospheric pressure
Boiling Point
The difference in temperature between the boiling point of a solution and the boiling point of the pure solvent
Boiling-Point Elevation
the movement of a solvent through a semipermeable membrane from low solute concentration to high solute concentration
