Aqueous solutions of unipositive cadmium; reactions of (CdI)22+(aq)Electron Transfer, part 146. For part 145, see ref. 1.

Abstract

Aqueous solutions 10−3 mol dm−3 in (CdI)2, prepared by treating O2-free solutions of Cd(ClO4)2 or Cd(O3SCF3)2 with Cd powder at 65 °C, can be handled by conventional methods; the comproportionation constant (Cd2+ + Cd ⇌ Cd22+) is estimated as 0.018 (24 °C, I = 1.14 M) and the formal oxidation potential as −0.45 V; this atypical state readily reduces I3, IrCl62−, pyridine complexes of (NH3)5RuIII, and superoxo derivatives of (NH3)5CoIII.
