On the oscilloscopic determination of rate constants of electrode reactions by means of square wave and sine wave current: I. The moment of zero diffusion polarization in the square wave case

Abstract

AbstractA new and simple derivation of the diffusion polarization as a function of time is presented for the case wherein a square wave current passes an electrode‐solution interface. The moment of zero diffusion polarization, which was already known to be 0.09, is calculated more precisely to be 0.094 of the whole period of the square wave signal. The consequences as regards the cyclic current step method for the determination of rate constants of electrode reactions, are discussed.
