Catalytic titrations of silver(I) applying the iodide-catalysed manganese(IV)-arsenic(III) indicator reaction in the presence of sulphuric acid
Abstract
A new catalytic potentiometric titration method for the determination of silver(I), applying the iodide-catalysed manganese(IV)-arsenic(III) indicator reaction in the presence of sulphuric acid, has been developed. The effect of the concentration of sulphuric acid and different ions, and of the mole ratio of manganese(IV) to arsenic(III) in the titrated solution, as well as of the titrand temperature on the conditions for the determination of silver(I) in solutions of various concentrations, was investigated. The error in the determination of 0.5 mu g/cm(3) silver(I) was less than 2%, with good reproducibility. Small quantities of 2-PAM iodide, as well as silver in a silver-zinc alloy were determined by the developed method.
