Summary Stoichiometric stability constants of Cu(II), Ni(II), Zn(II), Co(II), UO2(II) and Th(VI) phthalate have been determined by paper electrophoresis. Phthalic acid (0.005 mol dm−3) was added to the background electrolyte: 0.1 mol dm−3 HClO4. The proportions of C6H5C2O 4 − and C6H4C2O 4 = were varied by changing the pH of the electrolyte. These anions yielded the complexes, Cu C6H5C2O 4 + , Cu C6H4C2O4, Zn C6H5C2O 4 + , Co C6H5C2O 4 + , Ni C6H5C2O 4 + , UO2 C6H5C2O 4 + , UO2 (C6H4C2O4) 2 = and Th (C6H4C2O4)2 whose stability constants are found to be 103.0, 104.7, 102.6, 102.5, 102.3, 103.5, 1012.6 and 1013.4 respectively (μ=0.1, temp 40°C).
