The scope of this technical report is to present the background considerations which led to this compilation of potentials of the aqueous saturated calomel electrode compared to the cyclovoltametric data for a glassy carbon electrode in various solvent media. A tabulation of working potentials of this electrode pair in various solvent media is presented. A comparison of the cyclovoltametric scans for the ferricinium/ferrocene and deamethyl derivatized ferricinium/ferrocene redox couple system is presented and important features are discussed.
