Exchange reaction at polycrystalline lead electrodes in nitrate electrolyte

N. A. Hampson  and  D. Larkin  

Abstract

The results of impedance and double impulse measurements at polycrystalline lead electrodes in simple nitrate solutions are presented. The charge transfer process is the rate controlling mechanism. The value of the exchange current at a polycrystalline lead electrode in 0.05 M Pb(II) is ∼50 mA cm–2, the value of the charge transfer coefficient is ∼0.8. The enthalpy of activation for charge transfer is 12.6 kJ mole–1. At low [Pb(II)], impedance measurements indicate that active sites on the electrode were removed in which case the process of exchange was controlled by the process of lattice growth and dissolution.
