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
