Polarographic prewaves of electroreduction of nickel(II) in solutions of organic and inorganic complexing agents were observed by a number of workers. Especially the papers of Mark et al. ~, Tur'yan and coworkers 2, and Ikeda and Itabashi 3 should be mentioned. These prewaves in the case of a linea

While the electrode behaviour of the Ni(II)421 system in water was recently investigated and described in several papers I s, there is no detailed study, according to the authors' knowledge, of the Ni(II)~-system. There exist only a few observations on the presence of a prewave in the nickel(II)-iod
## 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 crystal
