Abstract: | The reaction under study is first order in the complex ion over the entire composition range of the mixed solvent. A minimum
amount of mineral acid is needed for completion of the reaction (formation of colorless products), but the rate is practically
acid-independent. The influence of solvent composition and some common ions on the reaction rate have been examined. A reaction
mechanism consistent with the rate behavior is proposed where water is shown as an active participant in the dissociation
process. A plausible explanation for the retardation effect of HSO4
− as against the accelerating effect of Cl− under water-scarce conditions is provided. |
