Electrochemistry of silver iodide the capacity of the double layer at the silver iodide-water interface

Abstract

A method is described for obtaining differential double layer capacities on silver iodide. Especially the influence of the nature and concentration of indifferent electrolytes was investigated, viz., the nitrates of Li·, K·, Rb·, NH4·, H·, Tl·, Mg··, Ba··, Co··, Cd··, Pb··, La···, Th····, the fluoride, chloride, and sulfate of K·, NaClO4 in 10−3 and 10−1M solutions. Capacities showed definite analogy with those on mercury. The influence of the counter ion was in the lyotropic order. The capacity of the molecular condenser, calculated with the assumption of absence of specific adsorption, was independent of the electrolyte content.
