Multistep electrode reactions, methods

Gaiser and Heusler53 have shown that the electrode reaction Zn2+ + 2e Zn proceeds in two steps Zn2+ 4- e Zn+ and Zn+ + e Zn(s). Van Der Pol et a/.,54 using ac coupled with the faradaic rectification polarography method, also concluded that this reaction is a multistep reaction. Hurlen and Fischer55 have studied this reaction in an acid solution of potassium chloride and... 

Many interesting processes occurring at the liquid/liquid interface involve coupled homogeneous chemical reactions. In principle, electrochemical methods used for probing complicated mechanisms at metal electrodes (61) can be employed at the ITIES. However, many of these techniques (e.g., rotating ring-disk electrode or fast-scan cyclic voltammetry) are hard to adapt to liquid/liquid measurements. Because of technical problems, few studies of multistep processes at the ITIES have been reported to date (1,62).
