| Abstract: | From the solubility of precipitated Co(OH)2 (s) determined radiometrically as a function of pH and ammonia content of the heterogeneous systems, the formation constants have been obtained for the following mononuclear hydroxo-, ammine- and mixed hydroxo-ammine-complexes: Co(OH)2, Co(OH)3?, Co(NH3)22+, Co(NH3)32+, Co(NH3)42+ and Co(OH)2 (NH3)2. The solubility of cobalt(II) hydroxide has also been calculated. The medium was 1M NaClO4 and the temperature 25° C. |
