Abstract

The kinetics of Cu(II) catalysed oxidation of hydrazine by hexacyanoferrate(III) is studied in acid medium. The stoichiometry of the reaction is 1:1. The first order condition is [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. Keywords: Hexacyanoferrate(III), oxidation, hydrazine hydrate
