The reduction of zinc(II) in concentrated lithium halide solutions

Abstract

The reduction of zinc(11) in lithium halide solutions has been studied using a.c. and d.c. polarography over an electrolyte concentration range of 1-20m for lithium chloride and lithium bromide solutions, and 1-12m for lithium iodide solutions. The degree of reversibility for the reduction increased with increase in electrolyte concentration in the order LiI > LiBr > LiCl. Faradaic impedance techniques were utilized to evaluate the rates of the electron-transfer processes.
