but not electrolyte solutions
a nonvolatile solute lowers the vapor pressure of a solution by preventing the escape of solvent molecules from the liquid
i.e. halp me i can has trouble getting out of this pool with these bears on top of me
the vapor pressure of a solution is directly proportional to the mole fraction of solvent present
when solute and solvent are looking for friendship, ideal situation, follows raoult's law
when solute and solvent are looking for a relationship, vapor pressure is lower than that predicted by raoult's law (less likely to stop procreating and escape)
trangle H soln LARGE AND NEGATIVE...negative deviation (give off heat, i happy here, not leaving)
triangle H soln LARGE AND POSITIVE...positive deviation (i am not compromising, give me heat, i g2g because you're a creeper)
colligative properties: freezing point depression, boiling-point elevation, osmotic pressure (depend on total concentration of solute particles)
1) nonvolatile solute elevates boiling point (I AM TRYING TO LEAVE BUT YOU'RE IN MY WAY)
2) nonvolatile solute lowers freezing point (I AM TRYING TO BE IN MY BED BUT YOU'RE IN MY WAY UNTIL I GET REALLY TIRED)
osmotic pressure is mimimum pressure that stops osmosis
in reverse osmosis, selectively permeable membrane acts as filter to remove solute particles
do not drink seawater, you will shrivel
