摘要：

Mean activity and osmotic coefficients have been determined at 25 degrees degrees for aqueous solutions of Co(en)(2)(NO1)(3), Co(pn)(3)-(ClO4)(3), K3Co(CN)(6) and [Co(en)(3)](2)(SO4)(3), by isopiestic comparison with potassium chloride solutions. At the concentrations required, these salts do not obey the simple laws for 3-1 or 3-2 types, requiring low values of 4 to represent the data by means of the Debye-Huckel equation. The solubilities of Co(en)(1)(NO3)(3)center dot H2O and K3Co(CN)(6) were determined to be 0.2749 and 1.311 m, respectively. Conductivity measurements were made on solutions of the same four electrolytes. A decided deviation from the Onsager limiting law was observed. The limiting values obtained for the complex ions are in agreement with those found by previous workers.
