The presence of NTA ( H3T) can affect the solubility of Pb(OH)2 in water. You know that the solubility product for the Pb(OH)2 is 1.61x10^-20, the Ka's for the hydrogen ions coming off of H3T are Ka1=2.18x10^-2, Ka2=1.12x10^-3, Ka3=5.25x10^-11.We also know that the formation constant for the complexation reaction is Kf=2.45x10^11 ( Pb^2+ T^3- --> PbT^- is the complexation reaction). Find the appropriate net reaction to describe the solubilization of Pb(OH)2 by NTA, and find the equilibrium constant for this net reaction.
