|
solvent
|
the dissolving medium in a solution
|
|
|
solute
|
the substance dissolved in the solvent to make a solution
|
|
|
aqueous solution
|
a solution with water as a solvent
|
|
|
saturated
|
a solution that contains as much solute as will dissolve at that temperature
|
|
|
unsaturated
|
a solution in which more solute can dissolve than is dissolved already at that temperature
|
|
|
supersaturated
|
a solution that contains more solute than a saturated solution will hold at that temperature
|
|
|
concentrated
|
a solution in which a relatively large amount of solute is dissolved in a solution
|
|
|
dilute
|
a solution in which a relative small amount of solute is dissolved in a solution
|
|
|
mass percent
|
expresses the mass of solute present in a given mass of solution (mass solute/mass solution x 100)
|
|
|
molarity (M)
|
the amount of solute in moles and the volume on the solution in liters (moles solute/liters solution)
|
|
|
standard solution
|
a solution in which the concentration is accurately known
|
|
|
dilution
|
the process of adding solvent to a solution to lower the concentration of solute (MV=MV, n=n)

equivalent of a base
|
the amount of base that can furnish one mole of hydroxide ions (OH-)
|
|
|
equivalent weight
|
the mass (in grams) of one equivalent of an acid or base
|
|
|
colligative property
|
a property that is dependent only on the number of solute particles present in solution
|
|
|
n=MV, V=n/M, M=n/V
|
n - moles
