In forming a chelate with a metal ion, a mixture of free EDTA
(abbreviated Y4–) and metal chelate (abbreviated MYn–4) can buffer
the free metal ion concentration at values near the dissociation
constant of the metal chelate, just as a weak acid and a salt can
buffer the hydrogen ion concentration at values near the acid
dissociation constant. This equilibrium is governed by the equation
where Kf is the association constant of the metal and Y4–, ?Y4– is
the fraction...
