Disintegration of lead-acid batteries gives rise to the formation of solid lead sulfate (PbSO4) (Anglesite). Will a precipitate of PbSO4 form if 2.5 molar EDTA is added to 0.08 molar lead sulfate in an ionic solution (1M) at pH 6?
Kf for PbEDTA complex is 2 x 10^18.
EDTA's molar fraction at pH 6 = 2.3 x 10^-5.
PbSO4 Ksp = 2.13 x 10^-20.
Solubility coefficients/activity for ionic solutions (1M) = 0.5042 fate 0.5221d.
