Abstract

Abstract The formation of nickel(II) complexes with sulfate and/or acetate has been studied at 25°C and ionic strength 1.0 by the polarographic method reported previously1). The results obtained reveal that complex species, NiOAc+, NiSO4, Ni(SO4)22−, Ni(OAc)(SO4)− and Ni(OAc)(SO4)23−, are present in the solution. The formation constants determined are:KNioAc=1.9, KNiSO4=3.7, KNi(SO4)2=2.6×10, KNi(OAc)(SO4)=1 and KNi(OAc)(SO4)2=∼3 at ionic strength 1.0.
