homogenous sys
soln
saturated solns
at given temp and pressure contain the max amt of solute that can be accomodated by solvent
nonelectrolytes
-subs that do not form ions when dissolved in water
- aqueous soln do not conduct electric current
ex of non electrolytes
estradiol
glycerin
urea
sucrose
electrolytes
form ions in soln

aq soln conduct electric current
ex of electrolytes
NaCl
HCl
atropine
strong electrolytes
completely ionized in water at all conc
ex of strong electrolytes
NaCl
HCl
weak electrolytes
partially ionized in water
ex of weak electrolytes
asa
atropine
colligative properties of a soln
dependent on total # of ionic and nonionic solute molecules in the soln

dependent on ionization but independent of other chemical prop of the solute
colligative prop
1. lowering of vapor pressure
2. elevation of boiling pt
3. depression of freezing pt
4. osmotic pressure
raoult's law
partial vapor pressure of each volatile component in a soln = prodt of mol fraction of the component in the soln and the vapore pressure of the pure component
vapor pressure
temp dependent but independent of the amt of liq and vapor
boiling pt
temp at w/c vapor pressure of liq = an external pressure of 760mm Hg
higher boilingpt
xoln of a nonvolatile solute than pure solvent (bec solute lowers vp of solvent)
osmosis
process @ w/c solvent molecules pass through a semipermeable membrane fr a region of dilute soln to one of the more conc soln
semipermeable membtrane
barrier through w/c only solvent molecules may pass
solvent molecules in conc soln
lower chemical potential than solvent molecules in a more dilute soln
osmotic pressure
pressure must be applied to the soln to prevent the flow of pure solvent into the conc soln
van hoff's equation
osmotic pressure as a fxn of the # of moles of solute h2 in the soln of vol
