A Theoretical Interpretation for the Difference Between Stability Constants of the Same Metal Complex Determined by Different Analytical Methods

The ion-exchange method tends to give higher values of the stability constant than those obtained from absorption spectrophotometry for the same complex. The reason for this difference was clarified by introducing an equation for the estimation of the amount of conversion between outer-sphere and in...

More Information
Summary:The ion-exchange method tends to give higher values of the stability constant than those obtained from absorption spectrophotometry for the same complex. The reason for this difference was clarified by introducing an equation for the estimation of the amount of conversion between outer-sphere and inner-sphere binding for M m + –L ℓ − complexes inside the hydration sphere of a sample metal cation.
