solutions Flashcards
homogenous mixture of 2 or more components is called
solution
pressure exerted by vapours over the surface of liquid
vapour pressure
rate of evaporation= rate of condensation
.
what is solubility
amount of solute in a saturated solution per 100g of solvent
vapour pressure is directly proportional to
temperature
vapour pressure is inversely proportional to
intermolecular forces and boiling point
features of an ideal solution
obeys Raoult's law observed pressure is equal to calculated pressure imf between a-a and b-b are equal to a-b delta h= 0 delta v= 0 delta s>0 delta g<0
ideal solutions example
bromoethane-chloroethane
benzene-toluene
mixtures that cant be separated are called
azeotropic mixture
the properties which depend on number of solute particles
colligative properties
when non volatile solute is dissolved in volatile solvent its vp increases
RLVP
when non volatile solute is dissolved in volatile solvent its vp decreases, thus bp increases
EBP
when non volatile solute is dissolved in volatile solvent its vp decreases, thus freezing point decreases
DFP
the flow of solvent molecules from higher conc. to lower conc.
osmotic pressure
the minimum pressure that must be applied to the solution side to prevent osmosis
osmotic pressure
