Summary
Stability constants of copper (II) and nickel (II) oxalates have been determined by paper electrophoresis. Oxalic acid (0.005 mol dm−3) was added to the background electrolyte: 0.1 mol dm−3 HClO4. The proportions of HC2O −4 and C2O 2−4 were varied by changing the pH of the electrolyte, these anions yielding the complex ions MHC2O +4 and M(C2O4) 2−2 , average values of the stability constants for which are 102.4 and 107.6 respectively for Cu(II), and 102.3 and 106.5 for Ni(II) (μ=0.1,30°).
