摘要：

Nickel(II) was shown potentiometrically to form successive 1:2 and 1:3 complexes with nitrate in dimethyl sulfone at 125°, and values of the formation constants were determined. An amalgamated nickel coil served as the indicator electrode, and the silver(I)-silver system was used as the reference electrode. These potentiometric results were confirmed by spectrophotometric measurements, and the ligand field spectra of the nickel(II) species involved were determined. The spectrum of nickel (I I) in the molten LiNO3-NaNO3-KNO3 eutectic at 125° was measured and found to correspond closely to that of the 1:3 complex. © 1968, American Chemical Society.
