✦ Synopsis

Manganese(III)-arsenic(III) reaction in the presence of sulfuric acid is proposed in this work as an indicator reaction for the kinetic determination of some antidotic oxime iodides. As 2-hydroxyiminomethyl-1-benzyl-3-methylimidazolium iodide, 2-hydroxyiminomethyl-3-benzyl-1-[3-(2-hydroxyiminomethyl-3-benzyl-1-imidazolio)-2-oxapropyl]-imidazolium diiodide, and 2-[(hydroxyimino)methyl]-1-methylpyridinium iodide catalyze the proposed reaction, a kinetic method for their determination in the range from 1.0 ϫ 10 Ϫ8 to 8.0 ϫ 10 Ϫ8 mol dm Ϫ3 was developed. The effect of some other antidotic oximes on the accuracy of these determinations was investigated.

The kinetics of the iodide-catalyzed reaction of manganese(III) with arsenic(III) in sulfuric acid solution are studied in this work. The reaction rate was followed photometrically at 486 nm. The conditions under which the iodide ions have a maximum influence were established and the kinetic express

The rate of reaction between arsenite and vanadate, catalyzed by osmium(VIII) was monitored using an automatic potentiostatic stat method. This was carried out by maintaining the preset potential of a platinum indicator electrode by addition of a 2 Â10 À3 M vanadate solution (titrant). The rate of a
