The reduction of Ag+-ions (exchange current density io and charge transfer coefficient a) dissolved in an equimolar mixture of KC1-AlCl3 is studied by the double pulse method. By a comparison with the exchange current densities of silver in LiCl-KCl-melts the influence of the different structures of the electrolytes on the charge transfer is investigated. The great difference in the activity coefficient of silverchloride (γAgCl [LiCl-KCl] = 2.2 and γAgCl[KAlCl4] =82.3) is rather determined by the very limited solubility of the Cl--ions in the AlCl4--sublattice than by the activity of the silver ion.

A Journal of Physical Sciences: Zeitschrift für Naturforschung A (ZNA) is an international scientific journal which publishes original research papers from all areas of experimental and theoretical physics. In accordance with the name of the journal, which means “Journal for Natural Sciences”, manuscripts submitted to ZNA should have a tangible connection to actual physical phenomena.
