Abstract
Magnesium deposition and dissolution processes in ethereal Grignard salt solutions using tetrahydrofuran as the solvent and Grignard salt which included , , and (R = methyl, ethyl, butyl, or benzyl) are reported. dissolution and deposition in these solutions are basically reversible with an overall mass balance close to zero for complete cycles. In prolonged deposition processes, the mass accumulated per mole of electron transferred was similar to , the equivalent weight of magnesium. However, deposition‐dissolution is not a simple two‐electron process, but involves adsorption‐desorption processes of species such as and/or . These adsorption processes lead the electrodes to devel p high impedance upon storage in these solutions (up to hundreds of thousands of ). However, this passivation is not stable, and breaks down as the electrochemical processes proceed. ©2000 The Electrochemical SocietyThis publication has 0 references indexed in Scilit:
