Additionally, we present new electrode electric potential data with measurements up to 150 C versus the Ag/AgCl electrode. Much of the literature on the CSE comes either from studies determining activity coefficients of aqueous species [6,7] or conditions related to field applications [5,8]. Similar to the Ag/ AgCl reference electrode, the CSE consists of an aqueous solution and a metal wire to form the electrochemical couple. ...
... In the case of the CSE, the aqueous solution is commonly CuSO 4 (aq) mixed with H 2 SO 4 (aq), and the metal wire is Cu(s). Previous investigations of the CSE electrode focused on conditions such as different concentrations of H 2 SO 4 (aq) and CuSO 4 (aq) in the reference solution and temperature dependences from ambient up to 60 C [5][6][7][8]. However, no studies were found that discussed its application and behavior at higher temperatures. ...
