Copper–copper(II) sulfate electrode in the Daniel-Jakobi galvanic cell. Copper–copper(II) sulfate electrode The copper–copper(II) sulfate electrode is a reference electrode of the first kind, based on the redox reaction with participation of the metal (copper) and its salt, copper(II) sulfate. It is used for measuring electrode potential and is the most commonly used reference electrode for testing cathodic protection corrosion control systems. The corresponding equation can be presented as follow: This reaction characterized by reversible and fast electrode kinetics, meaning that a sufficiently high current can be passed through the electrode with the 100% efficiency of the redox reaction (dissolution of the metal or
Estelle (given name) with only a peripheral profile in Sweden - a 2012 year-end tally would estimate that a total of 663 Swedish residents bore the given name Estelle - touched off a flurry of media debate with writer Herman Lindqvist, who has acted as a historical consultant to the Swedish Royal Family, expressing the extreme negative position thus: "Totally unexpected and inappropriateNo name for a future rulerEstelle sounds like the name of a nightclub queen". Conversely top Scandinavian royalty pundit Kjell Arne Totland () reacted positively, calling Estelle "a very nice name, rich in tradition yet modern". Estelle (given name) Estelle is
