The formal potential of the antimonous-antimonic couple in hydrochloric acid and a method for the determination of tripositive antimony

by Brown, Raymond A.

Abstract (Summary)
1. The antimonous-antimonic half cell formal potential has been found to be -0.746 in 3.5 weight formal HC1, -0.784 in 4.5 weight formal HC1, and -0.818 in 6.0 weight formal HC1 when the total antimony concentration is 3.20x10(-2) weight formal. 2. The dependence of the formal potential upon total antimony concentration and the ratio Sb(+III)/Sb(+V) has been studied. 3. Tripositive antimony has been determined in quantities ranging from 10 to 1,500 micrograms by coulometric titration in hydrochloric acid solutions containing bromide with electrolytically generated bromine using an amperometric end point.
