Abstract

The yields of oxidation, reduction in a flash corona discharge between a solid cathode andthe water surface are compared. As the cathode was used a system of five aluminum electrodes. As the gasmedium were tested air, oxygen, and nitrogen. The models of processes in the discharge suggest formation of atomic hydrogen in water vapor: H2O → H + OH. However, the reduction yield is equal to the Faraday value irrespective of the gas composition. In the presence of oxygen, oxidation prevails. The yield of Fe2 + oxidation in oxygen is about 190 reaction events per electron passed in the circuit; in air it is lower by a factor of 2, and in nitrogen the yield is equal to the Faraday value.
