Abstract

H5[AsMo10V2O40] can be used in Sb3+ KBrO3 volumetric determination as a reversible redox indicator. The experimental dates were statistically compared to those obtained using classic Sb3+ titration method, which use organic irreversible indicators. The statistic interpretations show good results.
