20 mL 0.0 25m cadmium (II) are mixed with V mL of 0.05 m EDTA
(V=0,5,10, and 15)
a) Express the titration reaction at pH = 5, 9 and
12
b) Express and calculate the conditional constants the conditional
dissociation constants for pH. At what pH is the most quantitative
reaction? express pCd scales as a function of EDTA volume
c) For each pH and for addition, calculate the concentrations of
cadmium and EDTA at equilibrium and plot the corresponding
curves.
