Unit 8
solution
homogenous mixture of a solvent & solute
solvent
substance that dissolves solute
solute
substance that is dissolved in solvent
mixture
combination of 2 or more pure substances in which they each retain individual chemical properties
suspension
mixture containing particles that settle out if left undisturbed
colloid
a heterogenous mixture of intermediate-sized particles that don’t settle out
soluble
a substance that can dissolve in a solvent
insolube
a substance that cannot dissolve in solute
solvation
the process surrounding solute particles with solvent particles to form a solution
miscible
two liquids that are soluble in each other in any porportion
immiscible
two solutions that can be mixed together but separate shortly after
electrolyte
ionic compounds who’s aqueous solution conducts an electric current
molarity
the # of moles of solute dissolved per liter of solution
molality
the # of moles of solute dissolved in 1kg of solvent
saturated
contains the max amount of dissolved solute for a given amount of solvent (at specific temp. and pressure)
unsatured
one that contains less dissolved solute for a given temp. and pressure than a saturated one
supersaturated
contains more dissolved solute than a saturated solution (at room temp.)
concentration
____ of a solution is a measure of how much solute is dissolved in a specific amount of solute or solvent
QUIZ 2: colligative properties
physical properties of solutions that are affected by the # of particles but not by the identity of dissolved solute particles
dilution
weakening or watering down something → decreasing a solution’s solute concentration
