Conjugate bases of tris(ethylenediamine)cobalt(III) and nitropenta-amminecobalt(III) in aqueous hydroxide–dimethyl sulphoxide mixtures
Abstract
The conjugate bases of tris(ethylenediamine)-cobalt(III) and nitropenta-amminecobalt(III) are characterized in aqueous hydroxide–dimethylsulphoxide mixtures, pKa values being determined using an acidity function derived from the solvent dependence of the rate of base hydrolysis of chloropenta-amminecobalt(III).
