Formation Constants of Sulfato, Acetato and Sulfatoacetato Complexes of Copper(II) at Ionic Strength 1.0

Nobuyuki Tanaka, Yu Saito, Hiroshi Ogino

Abstract

Abstract The polarographic method for the determination of the formation constants which is based on the measurement of the effects of acetate and/or other co-existing ions on the equilibrium of the substitution reaction, M+M′L\ightleftarrowsML+M′, has been developed, and applied to the study of the copper(II) complexes with acetate and/or sulfate ions. The formation constants obtained at 25°C and ionic strength 1.0 are: 2·0×10 for KCu(OAc), 1·1×102 for KCu(OAc)2, < 3 for KCuSO4, ∼3×10 for KCu(SO4)2, 4×10 for KCu(OAc)(so4) and ∼7×10 for KCu(OAc)(SO4)2.
