Abstract

"Silver and platinum, although not used extensively in industry, find considerable use in specialized work. Silver, because of its much lower cost, is used to a greater extent than platinum. Since silver has a high position in the electromotive series, it is very resistant to chemical attack. It is unaffected by alkaline conditions even at high temperatures and hence silver is used in ladles and molds for producing pure sodium and potassium hydroxides. This and its excellent electrical conductivity makes it a very useful material in circuitry.


It has been reported in the literature that when active metals such as magnesium, zinc, and cadmium dissolve anodically in aqueous solutions, a greater amount of metal is found in solution than indicated by Faraday's law. This deviation from Faraday's law has been explained as due to the chunk effect (disintegration), or to valencies less than that of the normal ion.


The present investigation was carried out with the intention of determining if a similar deviation occurs for the anodic dissolution of a noble metal such as silver. The existence of such a phenomenon with silver would necessarily be explained by a disintegration of the electrode rather than uncommon valence ion formation"--Introduction, page 1.
