Analytical Studies on the Oxidation of Some Hydrazine Derivatives with Ammonium Pentavanadate(V) Reagents

Abstract

A simple quick and convenient method has been developed for
the micro estimation of some hydrazine derivatives. The sample
(1-5 mg) is allowed to react with 2 mL of 0.3 N ammonium
pentavanadate(V) reagent and 10 mL of 10 N H₂SO₄. The unconsumed
reagent can be accurately titrated with 0.025 N ferrous ammonium
sulphate solution using N-phenyl anthranilic acid as
indicator. Standard deviation as well as coefficient of variation was
calculated for reproducible and accurate result. The accuracy of the
method is within ± 1%
