Electrode-Electrolyte Interactions Magnesium Anodes : : meta-Dinitrobenzene Cathodes
Abstract
The electrochemical dissolution of magnesium (AZ-21) and hydrogen evolution reaction on magnesium in Mg(ClO4)2, Sr(ClO4)2, NaClO4, and NaClO4- Mg(ClO4)2 electrolyte mix have been investigated. The electrochemical reduction of meta-dinitrobenzene in NaClO4 and Mg(ClO4)2 has also been studied. Polarization data indicate the corrosion current density of the magnesium electrode is much smaller in the NaClO4 than in the other electrolytes studied. In the NaClO4 - Mg(ClO4)2 electrolyte mix the corrosion current density of the magnesium electrode increases as the proportion of Mg(ClO4)2 is increased. In the mixed electrolyte system the magnesium electrode can exhibit two distinctly different corrosion current densities. These corrosion current densities are dependent upon the history of the electrode. The rate of meta-dinitrobenzene reduction in NaClO4 and Mg(ClO4)2 was found to be about equal. Even though the reduction rate in the two electrolytes was equal, different reaction products apparently were formed.
