The Potential of Inert Electrons in Sulfurous Acid Solution
<p>Certain reducing substances, such as sulfurous acid, formic acid, or oxalic acid, show in their chemical behavior a much smaller reducing power than that calculated from the free-energy changes attending their conversion into their ordinary oxidation products, sulfuric acid or carbon dioxid...
