Colligative properties depend on
the identity of the solute particles.
the concentration of the solute particles.
the physical properties of the solute particles.
the boiling point and freezing point of the solution.
Nonvolatile solutes
depress the freezing point and elevate the boiling point.
elevate the freezing point and depress the boiling point.
elevate both the freezing point and the boiling point.
depress both the freezing point and the boiling point.
Electrolytes affect colligative properties differently than do nonelectrolytes because electrolytes
are volatile.
have lower boiling points.
produce fewer moles of solute particles per mole of solute.
produce more moles of solute particles per mole of solute.
