It has been reported that Americans ingest a total of approximately 8 tons/day of lead. The drinking water standard for lead is 0.05 mg/L total soluble lead. One method for removing heavy metals such as lead is pH adjustment to precipitate the metal hydroxide. Using a logarithmic concentration diagram, determine the minimum solubility (S) of lead (in mg/L as Pb) in water. Be sure to include lead complexes with hydroxide. At what pH does the minimum solubility occur? Ksp for...
