Copper(II) Catalyzed Oxidation of Hydrazine Hydrate by Hexacyanoferrate(III)

Abstract

The kinetics of Cu(II) catalyzed oxidation of hydrazine by hexacyanoferrate(III) is studied in acid medium. The stoichiometry of the reaction is 1:1. The first order condition [N₂H₅] > [Fe(CN)₆³⁻] is maintained. The order of the reaction is unity with respect to Fe(CN)₆³⁻, fractional orders with respect to hydrazine and copper. The reaction is independent of variation of sulphuric acid and ionic strength. A suitable mechanism is proposed for the reaction
