The temperature difference between a solution's boiling point and a pure solvent's boiling point.
Boiling point elevation
the jerky, random, rapid movements of colloid particles that results from collision of particles of the dipersion medium with the dispersed particles
Brownian motion
a physical property of a solution that depends on the number, but not the identity, of the dissolved solute particles
Colligative property
a quantitative measure of the amount of solute in a given amount of solvent or solution
concentration
the temperature at which a liquid is converted into a crystalline solid
freezing point
the overall energy change that occurs during the solution formation process
heat of solution
henry's law
states that at a given temp, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid
colloid
heterogeneous mixtures, categorized according to the phases of their dispersed particles and dispersing mediums
the ration of the number of moles of solute dissolved in one kilogram of solvent
molality
the number of moles of solute dissolved per liter of solution
molarity
the ratio of the number of moles of solute in a solution to the total number of moles of solute and solvent
mole fraction
the diffusion of solvent particles across a semipermeable membran
osmosis
contains the maximum amount of dissolved solute for a given amount of solvent at a specific temperature and pressure
saturated solution
the maximum amount of solute that will dissolve in a given amount of solvent at a specific temperature and pressure
solubility
a type of heterogeneous mixture whose particles settle out over time and can be seperated from the mixture by filtration
suspension
contains more dissolved solute than a saturated solution at the same temperature
supersaturated solution
the scattering of light by colliodal particles
Tyndall effect
contains less dissolved solute for a given temperature and pressure than a saturated solution
unsaturated solution
the lowering of vapor pressure of a solvent by the addition of a nonvolatile solute to the solvent
vapor pressure lowering
describes a substance that can be dissolved in a given solvent
soluble
the maximum amount of solute that will dissolve ina given amount of solvent at a specific temperature and pressure
solubility
