Abstract:From extraction measurements, the individual extraction constant of the hexamminecobalt (III) cation, Co(NH3)6]3+, in water-nitrobenzene system has been determined 
$$(\log  K_{Co(NH_3 )_6 ]3 + }^i  = 10.5)$$
. Further, using known thermodynamic parameters and general relations, the stability constant of the complex Co(NH3)6]3+ in nitrobenzene saturated with water was evaluated for 25 °C in the form log betanb{Co(NH3)6]3+}=54.1.
