Abstract
The polarographic reductions of 1,8‐dinitronaphthalene, 5,6‐dinitroacenaphthene, 3,4‐dinitroacenaphthenequinone, and 4,5‐dinitronaphthalic anhydride, were studied in buffered solutions at four different pH values. The relative wave heights of the multiple waves could be interpreted reasonably in terms of certain electron changes. A semi‐empirical equation was derived to confirm certain electron changes in the polarographic reductions. These electron changes were also checked by coulometric measurements on electrolyses run at controlled potentials. Results indicated that in all but one instance there was agreement between the values for the electron changes obtained in the parallel analyses. The one exception was 3,4‐dinitroacenaphthenequinone.
