Abstract
The formal potentials and the kinetics parameters for the electrode process: Cr 2++2 e − = Cr o occurring at a mercury electrode in solutions of NaClO 4, NaCI, NaBr, and NaSCN, were determined from the analysis of irreversible anodic and cathodic chronocoulometric waves. The interaction of Cr(II) with Cl − was found to be negligible (equilibrium constant K <1) whereas the interaction with Br − and SCN − was weak ( K 1(Br −)=1 M −1 and β 2(SCN −) = 25 M −2). The results of the analysis of the formal rate constant of this and other amalgam forming reactions suggested that the formation of amalgam was the most important step in the whole process.
