✦ Synopsis

At

high ionic strength the ion pair (NrPy:+. nX-) or complex (NiPy,X,), n = 0, 1, 2; X-= Cl-, Br-. SCN-. N;. F-. NO;. CIO; ; is adsorbed at the surface of mercury electrode. Under specified conditions in chloride, bromide, and thiocyanates solutions the electroreduction is preceded by a crystalliration of a complex on the electrode surfxc.

The induciivc role of specifically coadsorbed Cl-ions is discussed.

The electrode reactions of the Fe(II)-NCS system occurring at mercury electrodes have been studied by using cyclic voltammetry and large scale electrolysis. The elatroreduction of Fe(H) in that system occurs with a fast transfer of the first electron. The resulting intermediate complex of iron(I) is
