|
polyvalent
|
each mole of the acid or base liberates more than one acid or base equivalent
e.g H2SO4 produces 2 moles of H+ and therefore 2 acid equivalents |
|
|
equivalent weight
|
refers to units H released per molecule
|
|
|
amphoteric/amphiprotic
|
can act either as an acid or a base, depending on its chemical environment
|
|
|
titration
|
a procedure used to determine the molarity of an acid or base by reacting a known volume of a solution of unknown concentration with a known volume of a solution of known concentration.
|
|
|
equivalence point
|
when H+ = OH-
|
|
|
the equation to calculate end point (titration)
|
VaNa=VbNb
|
|
|
Buffer
|
a mixture of a weak acid and its salt or of a weak base and its salt. buffer solution have the useful property of resisting changes in pH when small amounts of acid or base added
|
|
|
Henderson-Hasselbach equation
|
pH=pKa+log[conj base/weak acid]
