Chapter 13 Flashcards
The attractive interaction of solvent molecules with solute is called:
Solvation
When the solvent is water, the interaction is called:
hydration
The equilibrium between a saturated solution and undissolved solute is dynamic; the process of solution and the reverse process, ______, occur simultaneously.
crystallization
In a solution in equilibrium with undissolved solute, the two processes occur at equal rates, giving a
saturated solution
If there is less solute present than is needed to saturate the solution, the solution is
unsaturated
When solute concentration is greater than the equilibrium concentration value, the solution is
supersaturated
The amount of solute needed to form a saturated solution at any particular temperature is the ______ of that solute at that temperature
solubility
Liquids that mix in all proportions are
miscible
Liquids that do not dissolve significantly in one another are immiscible.
immiscible
The soluabilities of gases in a liquid are generally propotional to the pressure of the gas over the solution, as expressed by
Henry’s Law
Henry’s law =
Sg=KPg
Concentrations of solutions can be expressed quantitativly by several different measures, including
mass percentage
PPM
PPB
M=
Moles solute/L solution
m=
moles solute/Kg Solvent
A physical property of a solution taht depends on the concentration of solute particles present, regardless of the nature of the solute is called a
colligative property
_____ ___ expresses the lowering of vapor pressure.
Raoult’s law
____ _______ obey Raoults law
