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
can act either as an acid or a base, depending on its chemical environment
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)
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]
