Alkali Metal Reductions at Tungsten and Mercury Film Electrodes in Buffered Neutral Aluminum Chloride: 1-Methyl-3-Ethylimidazolium Chloride Molten Salts
Abstract
Alkali metal reductions from (M+ Li, Na, and K) buffered neutral A1C13: ImC1 melts at a bare 250-micrometer diameter tungsten electrode coated with a mercury film were studied. In the LiC1 buffered neutral melt, bulk Li deposition occurs before the cathode limit of the melt; however, the deposited Li reacts then rapidly with the imidazolium cation. Sodium and potassium are not deposited at the bare tungsten electrode in melts buffered with the appropriate alkali metal chloride. At the mercury film electrode (MFE), deposition and stripping of Li, Na, and K were observed at -1.18, -1.35, and -1.68 V in buffered neutral melts. By comparison to aqueous reduction potentials, the formal potentials for deposition of the pure alkali metals from buffered neutral melts are predicted from the experimentally determined formal potentials of the alkali metal amalgams in the melts.
