Abstract

The equilibrium potential of saturated zinc amalgam is studied as a function of concentration of free ethylenediamine molecules, [en], in the region [en] ≈ 0.001–1 M in solutions of pH 9.5, 10.5, and 11.5. At the concentration of zinc(II) ions 2 × 10–3 M and [en] = 1 M only simple trisethylenediamine complexes of zinc(II) form in all the solutions. At smaller [en] and pH 9.5 and 10.5, complexes Zn(en)2 2+ and Zn(en)2OH+ are also present; these are complemented at pH 11.5 by Zn(en)2(OH)2 at [en] ≈ 0.005–0.1 M. Stability constants for these complexes are calculated.
