Our previous work with the iridium/hydrazine system suggested the poss
ibility of a chemical reaction between the superficial iridium oxide a
nd the hydrazine molecules in the solution. In this work, we have adap
ted the Christov work to our experimental conditions and we have obtai
ned the algebraic equations which could account for the processes here
described. The use of these equations with our experimental results,
obtained from E-t curves confirms the hypothesis of a charge transfer
reaction between hydrazine and superficial Ir oxide.
