Abstract: Galvanic cell Ag|;AgNO₃ + HNO₃|; Ag₂O₃ (Pt) at 25° and at the same activity of Ag⁺ and H⁺ ions has the e.m.f. E° = 0.958 v. and the temp. coeff. dE°/dT = 0.97 mv./degree. The standard potentials are E°₃ = 1.757 v. for Ag₂O₃, Ag and E°23 = 1.711 v. for Ag₂O₃, Ag₂O₂. The standard thermodynamic values of Ag₂O₃ are δG° = 29.0 kcal./mole, δH° = 7.9 kcal./mole, and S° = 25 cal./degree-mole
