Abstract

In addition to kinetic measurements, the authors followed the potential of three oriented sections of Al monocrystal during its reaction with aqueous NaOH solution. The time dependences showed a shift of the potential to more positive values; the difference between the stationary, E_st, and initial, E₀, values was dependent on the orientation of the section and was related to its reactivity. Potential oscillations were observed on the (110) crystal face in the concentration region from 2 to 8 mol dm^-3 NaOH, and their period and amplitude were measured. The stationary potential was a parabolic function of the reaction rate at concentrations of NaOH from 0 to 5 mol dm^-3.
