Abstract : The standard potentials for the cells Ag/AgCl in (Li,K)Cl//AgNO3 in (Li,K)NO3/Ag at 400C and Ag/AgCl in (Li,K)Cl//Ag2SO4 in (Li,Na,K)2SO4/Ag at 550C are 0.687 and 0.718V, respectively, on the mole fraction scale. The cells Ag/AgNO3 in (Na,K)NO3//(Na,K)NO3/NO2, O2, Pt, or Au and Ag/Ag2SO4 in (Li,Na,K)2SO4//(Li,Na,K)2SO4/SO3, O2, Pt show reversible behavior and good Nernstian response on variation of the partial pressures of the gases by means of a versatile gas-flow system. The standard free energy of formation of AgNO3 was found. (Author)
