Abstract

An experimental procedure for the interrelation of standard electrode potential series in different solvents is described. The standard molar potentials at 25°C of the cesium amalgam electrode in water, ethylene glycol, and methanol are -1.950, -1.881, and -1.800 V, respectively, with ultimate reference to NHE in water. The net contribution of the solvent to the liquid junction potential at the junctions water-ethylene glycol, water-methanol, and methanol-ethylene glycol is 0.028, 0.007, and 0.021 V, respectively (the positive side of the "solvent" junction potential being indicated by the first solvent mentioned for each pair). © 1978.
