Compute the fraction of edta is completely unprotonated

Reference no: EM13195301

EDTA is a hexaprotic system with the following pKa values: pka1= 0.00 pka2=1.50 pka3=2.00 pka4=2.69 pka5=6.13 pka6=10.37 The distribution of protonated forms of EDTA will therefore vary with pH. For equilibrium calculations involving metal complexes with EDTA, it is convenient to calculate the fraction of EDTA that is in the completely unprotonated form, Y4- (see the figure). This fraction is designated ?Y4-. Calculate ?Y4- at the following two pH values pH = 3.85 pH= 10.90
