Definition
as compared to a pure solvent, a solution has _____
Term
solute prevents the solvent particles from organizing into a crystal structure
Definition
why do solvents have a lower freezing point?
Term
adding solute prevents solvent from leaving the surface of the liquid and going into the gas phase
Definition
why do solutions have a higher boiling point?
Term
osmosis
Definition
a passive process of the movement of water through a semi-permeable membrane
Term
from a higher concentration of water to a lower concentration of water
Definition
how does the water move in osmosis?
Term
cell membranes
Definition
an example of a semi-permeable membrane
Term
hypertonic solution
Definition
high concentration of solute
Term
hypotonic solution
Definition
lower concentration of solute
Term

Term
(part / total) x 100
Definition
formula for percent composition
Term
6.022 x 10^23 of any formula unit
Definition
a mole
Term
molar mass
Definition
the mass of a mole
Term
solubility
Definition
maximum amount of a solute that can be dissolved in a solvent; depends on temperature
Term
miscible
Definition
refers to liquids that can be mixed in any proportion
Term
saturated solution
Definition
contains solute at the solubility limit
Term
supersaturated solution
Definition
contains solute at a concentration greater than the solubility limit
Term
