Abstract
The interaction between lead(II) and methanesulfonate ions was studied by conventional d.c. polarography at 2.0 M ionic strength and pH 4.0. Two stepwise lead complexes are formed in solution: [Pb(CH3SO3)]+, ß1 = 1.76 ± 0.03 M−1 and [Pb(CH3SO3)2], β2 = 0.25 ± 0.05 M−2 which are reversibly reduced at the DME. At high ligand concentrations, above 1.0 M, a third lead complex, [Pb(CH3SO3)3] 433= 0.30±0.07M −3, is formed.
