Measurements on Galvanic Cells Involving Solid Electrolytes

Electromotive force measurements on galvanic cells involving solid electrolytes have been made in order to obtain the standard molar free energy of formation of $\mathrm{CoO}$, $\mathrm{NiO}$, ${\mathrm{Cu}}_{2}O$, ${\mathrm{Ag}}_{2}S$, ${\mathrm{Ag}}_2\mathrm{Se}$, $\mathrm{PbS}$, and several phases of the system Ag‐Te at elevated temperatures.
