Abstract:
The kinetics of reduction of Fe(III) ions by sulphate ion have been investigated in perchiorate medium. In all cases the reaction is first order in sulphide ion and second order in ferric ion. Over all the reaction is found to be third order. The decrease in the third order rate constant ko for the reaction of iron (III) with sulphide ion found with added sulphate ions. ko decreases to a very low insignificant value. This is interpreted in terms of complex formation between ferric ions and sulphate ions, the complex not reacting with sulphide ions. From the variations of ko with concentration of sulphate ions the type of complex is distinguished. Formation constant are determined for the complex under experimental conditions.
