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.
