Abstract
The electrochemical reactivity of different nitrogen oxides or their absorption products in sulfuric acid was investigated by potential scan measurements. Experiments were carried out at 23°C with platinum electrodes. Among the substances studied only and exhibited well‐defined oxidation and reduction currents. The electrochemical reactions of in were studied in detail by using a rotating disk electrode. Mass transport limited currents were observed for both oxidation and reduction. From the variation of the limiting current with rotation rate the diffusion coefficient of was determined to be .
