| Abstract: | Lead speciation in many aqueous geochemical systems is dominated by carbonate complexation. However, direct observations of Pb2+ complexation by carbonate ions are few in number. This work represents the first investigation of the equilibrium  over a range of ionic strength. Through spectrophotometric observations of  formation at 25 °C in NaHCO3-NaClO4 solutions,  formation constants of the form  were determined between 0.001 and 5.0 molal ionic strength. Formation constant results were well represented by the equation: |
