Abstract
A room-temperature molten salt, 1-ethyl-3-methylimidazolium tetrafluoroborate with adequate purity was obtained simply by the reaction of 1-ethyl-3-methylimidazolium chloride and tetrafluoroboric acid. Silver tetrafluoroborate dissolves up to ∼0.2 mol dm−3 in at room temperature. Electrochemical deposition and dissolution of silver on a platinum electrode were found possible in containing The reduction of monovalent silver species is electrochemically irreversible, the rate constant being estimated to be cm s−1. The diffusion coefficient of Ag(I) is calculated to be cm2 s−1, suggesting that Ag(I) exists as a substantially bare cation in © 2001 The Electrochemical Society. All rights reserved.
