On the oximine complexes of transition metals, Part CXIII Protolytic equilibria in the solutions of some complexes of the type [Co(Diox.H_2 AB] with alpha-benzyldioxime and alpha-furyldioxime

11 complexes of the type [Co(Diox.H)_2 AB]^n (Diox.H)_2-alpha benzyldioxime (Diphenylglyoxime: Dif.H_2), alpha-furyldioxime furox.H_2), A, B, - CN^-, NO_2^-, HSO_3^-, SO_3^2-, H_2O, amine) were obtained by various substitution reactions, and characterized by middle IR and electronic spectral data. The protolytic equilibria: [Co(Diox.H)_2 AB]^n \leftrightarrows H^+ [Co(Diox.H)(Diox)AB]^n-1 + \leftrightarrows H^+ of these complexes in aqueous solutions were studied by potentiometric and spectrophotometric measurements (in Britton-Robinson buffer solutions). The complicated character of these processes (5 equilibria in a wide pH range) was discussed
