説明
Abstract A method for evaluating a true stability constant termed the “absolute stability constant” is presented and the absolute stability constants for some first complexes of iron(III) with inorganic anionic ligands, are evaluated by spectrophotometric measurement and mathematical treatment. The K1 values obtained are: 2.1 for Fe(ClO4)2+, 7.6 for FeCl2+, 3.6 for FeBr2+, 383 for Fe(SO4)+ and 3.2 for Fe(NO3)2+ at I = 0.4 M and 20°C. These values are much larger than the apparent constants, that is, than the values which have conventionally been reported as “stability constants”.
